  • Everything’s Popping! (With the OU and Popcorn)

    Rabbi Aharon Brun-Kestler

    According to www.popcorn.org, Americans consume in excess of 17 billion quarts of popped popcorn annually – or about 54 quarts for every man, woman and child. The world’s primary popcorn producing region is the Midwestern United States and an entire food industry has grown up around it. Why is popcorn so popular? Because it is nutritional, versatile and delicious! Popcorn is an easily prepared whole grain snack. Without butter or other additions, popcorn is about 31 – 55 calories per cup. It goes with almost anything, and can accept a wide variety of flavor enhancements. Today, you don’t have to do much work to enjoy this treat. While of course one can still purchase raw popcorn and either air or oil pop it, microwave popcorn has become ubiquitous. In fact, the first test of the microwave on food in the 1940’s was popcorn. By the 1990’s this product niche had over $240 million in sales. And while salt and butter remain the most popular flavors, today’s marketplace is full of gourmet popcorns -- and not only caramel. There are cheese flavors, chocolate covered, nut balls and new flavor trends like jalapeno, too.

  • Here’s Something to Chew On: How Granola Brings Benefits to Health-Conscious Consumers

    Rabbi Yisroel Bendelstein

    Americans today are looking for alternatives. This trend has manifested itself in many different areas but is perhaps the most pronounced in the health sector. How often do we hear about alternative medicine? As a result, more and more Americans are electing to have a homeopath, chiropractor, or kinesiologist be their primary care physician in place of the more conventional medical doctor. In a word, Americans are looking to lead a more ‘natural’ lifestyle. After all, what can be better than what nature itself has to offer?

  • Brandy Is Dandy, But Needs Special Attention to Be Kosher as Well

    Rabbi Yaacov Mendelson

    Brandy is short for brandywine and is derived from the Dutch brandewijn, meaning burnt, or distilled, wine. The alcohol for brandy is produced by fermenting fruits to produce wine. Because fermentation is a result of the action of microbes in yeast, there is a natural limit to the alcohol content of the fermented material. When the alcohol concentration reaches a level of about 12 percent, fermentation stops. The reason is that the alcohol kills any remaining yeast so that no more alcohol is produced; the limit of alcohol content in wine, therefore, is around 12 percent. There is, however, a type of bacteria, called acetobacter, which thrives on alcohol, turning it into vinegar, thereby souring the wine. Thus, wine is ordinarily subject to two drawbacks in quality: The one is a limit to its strength, the other, a limit to its shelf life.

  • Yoshon

    Rabbi David Gorelik

    The source for the laws pertaining to Yoshon are found in Vayikra (23:9-14). These laws are applicable to the Chamishas HaMinim of barley, oats, rye, spelt and wheat. These grains are Yoshon if they took root prior to Pesach. If the grains did not take root prior to Pesach then they are chadash until the subsequent Pesach. There is a halachic dispute if the hashrashah (grain taking root) must be 3 days or two weeks prior to Pesach. The laws of chadash do not apply to other grains such as rice, corn and buckwheat.
