How to Dry Fresh Herbs

How to Dry Fresh Herbs

Drying your own herbs is easy and painless — as long as you know what you’re doing. Different herbs require different techniques; some popular herbs don’t usually take well to traditional methods of drying at all.

Drying Herbs: The Basics

No matter what drying method you are using, there are a few basic steps that need to be followed.

1. If you are harvesting herbs directly from your garden, make sure to pick them at their peak, when their flavor is the strongest. For most herbs, that means when the buds have just appeared, but are not fully open yet.
2. The best, and only, herbs you should dry are fresh herbs. Remove any yellowed, dried or otherwise unhealthy looking leaves.
3. Clean your herbs before drying them. Run the stems under cool, running water, removing any dirt or bugs, and pat dry thoroughly with a paper towel. Herbs should be totally, completely dry before you start the drying process.
Bunching

Good For: Marjoram, lavender, chives, sage, oregano, rosemary, mint, catnip, lemon balm.
Method: Tie 5-8 stems together in a bundle, and place bundle in a paper bag, stems extending out from the opening. Hang the bag in a dark, warm place with good air circulation. The temperature should be about  21-26 degrees C. Let dry for two to four weeks, checking periodically to make sure the bundle hasn’t come loose.

Tray/Screen Drying

Good For: Basil, dill, parsley, cilantro, thyme, oregano, rosemary.
Method: Remove stalks and stems. Handle leaves gently, and cut large leaves into small pieces. Place on a drying tray, old window screen or baking sheet. If you’re stacking trays, place a spacer in between each try so the herbs have air circulation. Place in a warm, dark area and stir daily until thoroughly dried.

Oven Drying

Good For: Basil, bay leaves, mint, sage.
Method: This works best for gas ovens. On a baking sheet, arrange individual leaves so that no leaves are touching. If you have enough for more layers, place a paper towel between each. Do not turn on the oven. Leave overnight.

La ONU invita a comer insectos para combatir la obesidad

La ONU invita a comer insectos para combatir la obesidad

 

En todo el mundo se consumen 1.900 especies de insectos, la mayoría de ellos en África y Asia. Naciones Unidas acaba de sugerir que extender esta práctica a países occidentales podría ayudar a combatir la obesidad y mejorar el medioambiente; y combatir, al mismo tiempo, el hambre en el mundo.

La idea la ha sugerido el departamento forestal de la FAO (la organización de la ONU para la alimentación y la agricultura), durante una Conferencia Internacional sobre Nutrición y Seguridad Alimentaria en Roma (Italia). “En las culturas occidentales tenemos prejuicios y pensamos que como los insectos se comen en países en desarrollo no pueden ser buenos”, admite Arnold van Huis, de la universidad holandesa de Wageningen, y autor de un informe que defiende esta tesis.

Este documento sostiene que muchas especies de insectos contienen la misma cantidad de proteínas y minerales que la carne y el pescado, pero además son ricos en algunos ácidos grasos que han demostrado sus beneficios para la salud.

Eva Muller, representante de la FAO, ha recordado que cada vez son más los restaurantes occidentales que incluyen insectos en sus cartas; como los saltamontes del danés Noma, considerado el mejor restaurante del mundo. Pero además de ayudar a combatir la epidemia de obesidad en los países industrializados (que afecta ya a 500 millones de personas), la FAO considera que el consumo de insectos supondría un menor daño ecológico, ya que su producción requiere menos tierras y emisiones de gases a la atmósfera.

Five Things That Make Daters ‘Click’

5 Things That Make Daters ‘Click’

 

It’s what everyone hopes for when they go on a first date, and the first thing friends will ask you about: “did you click?”  And what I always found interesting about “clicking” with someone—feeling like you’ve connected or formed a meaningful bond with them—is how quickly you can know it’s happened…or hasn’t happened. In fact, sometimes it can feel like it only takes a few minutes of talking to a stranger, from romantic prospects to new friends, to know whether you’ve bonded.

But what actually makes that “clicking” feeling happen…and how long does it really take? Does it come down to common interests?  Attraction?

The paper, “Making the Connection: Social Bonding in Courtship Situations,”  found that connection was all about words—how they were delivered, when, and for how long. That’s made men and women in the study feel like they were clicking and had forged a meaningful relationship…yes, even in the span of four minutes!

So what exactly got them to feel that way? Researchers had the speed daters fill out pre- and post-date surveys and wear audio recording devices during the dates. They found that:

  • Women felt a sense of connection to men that used appreciative language (like “good for you!”) and sympathy (like “that must have been tough on you”).
  • Women also clicked with men who interrupted them—not by changing the topic of conversation, but by finishing a sentence or adding to it. Even in four short minutes, it demonstrated understanding and engagement.
  • Asking too many questions, however, was a no-no. Sounds counterintuitive, but women in the study felt disconnected when they had to ask men questions (because the conversation was lagging) or when the men asked them questions (because they had nothing else to say).
  • Varying one’s speech to get louder or softer also endeared couples to each other—anyone who’s been on a date with a monotone speaker can probably attest to that!
  • Finally, both men and women were in agreement that they felt like they clicked when the focal point of the conversation was the woman, and the man’s “job” was mainly to demonstrate alignment with and understanding of his date.

Origen del día de San Valentín

Origen del día de San Valentín

Hubo un emperador romano llamado Valente, quien gobernó desde el 364 d.C. hasta el 378, él tenía un hermano mayor que se llamaba Valentiniano.

Mientras Valente gobernaba las provincias Orientales del Imperio con capital en Constantinopla, Valentiniano gobernaba las provincias Occidentales con capital en Milán.

En esa época eran constantes y periódicas las persecuciones de los cristianos y la Iglesia cristiana siempre ha recordado a sus mártires y a menudo les ha recompensado con el título de Santo, y los días en que eran ejecutados eran declarados sagrados en su memoria. Ahora por ejemplo cada día del año tiene sus mártires o santos correspondientes. Por supuesto en ese tiempo muchos cristianos (incluidos los mártires) eran de descendencia romana y tenían nombres romanos. Al menos dos de estos mártires se llamaban Valentinus (Valentín para nosotros) y el día en que se conmemoraba su memoria era el 14 de Febrero, que se recuerda por lo tanto como el día de San Valentín

En la antigüedad, la mortalidad infantil era bastante elevada de modo que era importante tener muchos hijos. Por lo tanto, las personas que, por cualquier razón, tenían pocos hijos o ninguno se consideraban a sí mismas como malditas o bajo alguna maldición y se sometían a ritos religiosos o místicos para asegurarse la fertilidad. Los romanos tenían un lugar sagrado donde (según la leyenda) la loba había amamantado a Rómulo y Remo, el prímero de los cuales fundó Roma. Ese lugar era llamado el Lupercal, de la palabra latina lupus, que significa ‘lobo’.

En ese lugar, todos los 15 de Febrero tenía lugar una celebración llamada Lupercalia, durante la cual se sacrificaban animales. Se preparaban correas con tiras ensangrentadas de la piel del animal y los sacerdotes corrían entre la multitud golpeándola con esas correas. Se creía que los que recibían golpes se curaban de la estirilidad. Naturalmente, la gente que quería hijos concurría en masa a la celebración y luego iban corriendo a casa a ‘trajinar’ para tener el hijo. En consecuencia, las festividades lupercalianas estaban asociadas con el amor y el sexo.

En el año 494, el papa Gelasio prohibió esta celebración pagana, pero las prohibiciones nunca salen como uno quiere, y el festival continuó bajo otro nombre. Así que el festival lupercaliano del 15 de Febrero pasó al 14 de Febrero, día de San Valentín (seguramente porque éste era un santo muy popular). Más tarde se crearon leyendas para explicar que San Valentín era protector de los enamorados, una manera de esconder el rito antiguo de la fertilidad.

Y ha llegado hasta nuestros días… aunque ahora no nos dedicamos a que nos azoten con tiras de animales ensangrentadas, estamos en la época del consumismo y es más rentable para las grandes empresas que gastemos el dinero en felicitaciones, pulseras, anillos o cualquier otro objeto.   :)

The Legend of St. Valentine

The Legend of St. Valentine

The history of Valentine’s Day–and the story of its patron saint–is shrouded in mystery. We do know that February has long been celebrated as a month of romance, and that St. Valentine’s Day, as we know it today, contains vestiges of both Christian and ancient Roman tradition.

But who was Saint Valentine, and how did he become associated with this ancient rite?

The Catholic Church recognizes at least three different saints named Valentine or Valentinus, all of whom were martyred. One legend contends that Valentine was a priest who served during the third century in Rome. When Emperor Claudius II decided that single men made better soldiers than those with wives and families, he outlawed marriage for young men. Valentine, realizing the injustice of the decree, defied Claudius and continued to perform marriages for young lovers in secret. When Valentine’s actions were discovered, Claudius ordered that he be put to death.

Other stories suggest that Valentine may have been killed for attempting to help Christians escape harsh Roman prisons, where they were often beaten and tortured. According to one legend, an imprisoned Valentine actually sent the first “valentine” greeting himself after he fell in love with a young girl–possibly his jailor’s daughter–who visited him during his confinement. Before his death, it is alleged that he wrote her a letter signed “From your Valentine,” an expression that is still in use today. Although the truth behind the Valentine legends is murky, the stories all emphasize his appeal as a sympathetic, heroic and–most importantly–romantic figure. By the Middle Ages, perhaps thanks to this reputation, Valentine would become one of the most popular saints in England and France.

 

Origins of Valentine’s Day: A Pagan Festival in February

While some believe that Valentine’s Day is celebrated in the middle of February to commemorate the anniversary of Valentine’s death or burial–which probably occurred around A.D. 270–others claim that the Christian church may have decided to place St. Valentine’s feast day in the middle of February in an effort to “Christianize” the pagan celebration of Lupercalia. Celebrated at the ides of February, or February 15, Lupercalia was a fertility festival dedicated to Faunus, the Roman god of agriculture, as well as to the Roman founders Romulus and Remus.

To begin the festival, members of the Luperci, an order of Roman priests, would gather at a sacred cave where the infants Romulus and Remus, the founders of Rome, were believed to have been cared for by a she-wolf or lupa. The priests would sacrifice a goat, for fertility, and a dog, for purification. They would then strip the goat’s hide into strips, dip them into the sacrificial blood and take to the streets, gently slapping both women and crop fields with the goat hide. Far from being fearful, Roman women welcomed the touch of the hides because it was believed to make them more fertile in the coming year. Later in the day, according to legend, all the young women in the city would place their names in a big urn. The city’s bachelors would each choose a name and become paired for the year with his chosen woman. These matches often ended in marriage.

Count Sheep to Fall Asleep.

The practice of counting sheep to fall asleep is so engrained in our culture that it’s best described as a stereotype. But does it actually work? Definitely — but it depends on the person. Often, we’re kept awake at night by stress or by planning what we need to do in our waking hours. The key is to turn your mind off and relax. Counting sheep is a simple and repetitive activity that some people find relaxing. For others, though, it can actually add more stress. Our advice? If it’s not working for you, find another strategy. If it does, great!
