As Passover and National Grilled Cheese month come to a close, the question remains: What would a Jewish grilled cheese look like, anyway? Does the cheese have to be special? Would it involve bagels and challah? Pita and tabbouleh? Matzoh (shrieks of despair and horror)? For some, being Jewish involves cultural imagery or flavor. You may see this at your local deli described as "kosher-style," evoking tastes of what grandma made in the old country, but without the religious restrictions. Many Jews, however, observe the complex dietary laws of kashrut (kosher is the more commonly recognized term).
Let's break down our grilled cheese ingredients to see how to make a Jewish masterpiece.
It just so happened that National Grilled Cheese month came at the same time as Passover--which is cruel, as this makes the bread aspect of the grilled cheese a little complicated.
As the story goes, the Israelites were slaves in Egypt. They were so harried in fleeing from the Egyptians that bread didn't have time to rise, or become leavened. And Matzah was born. In order to be Kosher for Passover, houses needed to be complete rid of "chametz" (leavened food). For a super Jewish (and crunchy) grilled cheese, Matzah is one way to go.
When Passover is not in play, there are a variety of Jewish bread recipes to use, from rye and sourdough to pita.
Kosher bread is not difficult to make, as the ingredients, utensils and cookware are all fairly standard. Cheese is far more complicated when it comes to the issue of kashrut.
The products used to manufacture cheese--particularly hard cheeses--are difficult to keep kosher because of how cheese is processed through heating and cooling.
The main dairy guru from the Orthodox Union (the OU stamp of approval that appears on some kosher products), Rabbi Avraham Gordimer, provides a 20 minute podcast, detailing complexities of "hekshering" (kosher-izing) cheese, from the plate-heat exchangers and spray nozzles to the cheese vats. It's like listening to a tax accountant for the Jewish food world. (One has to wonder if some of these intricacies aren't merely invented in order to give people jobs.)
Surprisingly, cheese is not a focus of Jewish culinary culture. Perhaps this is because in kashrut (the laws of kosher), it is important to have all milk and meat separated. Kosher homes will even have two sets of cutlery and utensils for dairy and for meat. (This derives from biblical passages that forbid the bathing of a baby goat in its mother's milk.)
So, any grilled cheese that involves chunks of meat is highly non-Jewish.
The most contentious piece of kosher cheese production surrounds rennet. Rennet is an enzyme that splits milk into curds and whey, and most forms are derived from the stomach linings of animals. Although rennet is not considered a meat product (so we're in the clear for the separating milk and meat issue), if the animal itself is considered non-kosher then there's a problem. There are animals famously forbidden (like pig), and specific laws for proper slaughtering.
The ancient authorities discussed the rennet issue at length (oh, to be a fly on that wall), and modern Jews vary in their observance and need for a hechsher (kosher supervision) based on the different interpretations.
It's not quite clear, even to Jews, why people keep kosher. Some say it's for health reasons or animal cruelty awareness, others believe it derives from ancient practices, where the Israelites were attempting differentiate themselves from other peoples. Many simply view it as a religious obligation without a purpose, other than the contemplation of the sacred and the profane.
Despite the obstacle of Passover coinciding with National Grilled Cheese month, people on the web got creative with their Jewish grilled cheeses.
Grilled Shane experimented with the themes of holiday, like adding charoset (a sweet mixture of nuts, apples and cinnamon meant to symbolize the mortar of the pyramid builders). He had a little shout out to Easter brie as well. Doves and Figs offers a Drunken Passover Grilled Cheese, completely kosher down to the Cabot cheese.
And on the opposite end of kosher (traif), A blog by Candace Karu involves bacon wrapped matzah balls...with grilled cheese on the side.
Leah Koening at My Jewish Learning figured out how to make a challah grilled-cheese for her pre-Passover purging. Perhaps after break fast on Tuesday evening, a famous Los Angeles pretzel-challah grilled cheese may be a worthy experiment.
