Food Fact | Bay Leaves



I have a strange thing about bay leaves -- I don’t like to cook with dried bay leaves in dishes that they're meant to be eaten. I feel like dried bay leaves would be too unappetizing to chew. So, I buy fresh bay leaves if they’re required to be eaten. Strange? I don’t know. I decided to look into bay leaves a bit more, because no one really questions ‘why’ when it comes to bay leaves.

According to Wikipedia, there are six different kinds of bay leaves used in cooking: 1.) Mediterranean bay laurel, 2.) California bay leaf, 3.) Indian bay leaf, 4.) Indonesian bay leaf, 5.) West Indian bay leaf, and 6.) Mexican bay leaf. Penzey Spices lists a seventh – Turkish bay leaf. (Upon seeing this, I’m quickly reminded that I also steer clear of Indian bay leaves because they’re so freaking big. I figure they can’t be flavorful that big. It has to be like big, flavorless beefsteak tomatoes or something.) On another note, in the old españolie, one would say ‘laurel,’ but I wonder if that refers to bay laurel or Mexican bay leaf. 

Greeks, Arabs, the French, Southeast Asians, and North Americans all use bay leaves in cooking soups, stews, seafood, meats, and sauces. Serious Eats says it used to bring out the taste of warm spices and meaty flavors. I personally use it in gumbo, red beans, smothered chicken, and brothy soups. I feel like it doesn’t taste like much, but if you leave it out of a recipe, you can taste it’s missing something.  

Despite popular belief, bay leaves aren’t poisonous, and bay leaves may be eaten without dying a painful culinary death of humans. Although, there are sources (i.e. loads of studies from the 1908s) that show bay leaves can repel and/or kill insects due to cyanide released in the crushed leaves. (This seems like contradictory information, but I’m not a physician or an entomologist.) 

Most importantly, my thoughts on avoiding the consumption of dried bay leaves may not be so strange after all; Wikipedia says that because bay leaves stay stiff throughout cooking, swallowing large pieces can scratch the digestive tract or cause choking. (So, I’m not so crazy after all!)  On a medical tangent, it seems like bay leaves have been shown to improve insulin function in vitro, for all your ladies with a case of the babies worried about childhood diabetes. (Other spices that have been reported to be hypoglycemic include fenugreek, garlic, turmeric, cinnamon, cloves, cumin, ginger, mustard, curry, and coriander.)
Overall, this exercise in facts on bay leaves has proven to actually create more questions than it answers. Oh well.
