Passover, which this year begins at sundown next Monday, is an eight-day observance of the story of the Exodus, in which the ancient Israelites were freed from slavery in Egypt. It is also a harvest festival from ancient Israel, and the grain that was celebrated was barley.

This holiday marks the time of year when Jews are perhaps most careful about what they eat and the ingredients with which they cook.

The laws of kashrut, which govern the diet in the Jewish tradition, are very strict for Passover. The most familiar restriction is the law against eating or possessing leavened bread, or chametz, based on Exodus 12: 18-20. Jews sanctify their homes for the holiday by removing forbidden foods from refrigerators and pantries and checking every corner and surface for chametz.

The constraints on food aren’t the only rules in conjunction with Passover, but they are probably the most visible. “We are commanded not to eat leavened bread products, and the way we understand that in the Jewish tradition is that we do not eat anything made of these five grains: wheat, oat, barley, spelt or rye,” said Rabbi Frederick Reeves of The Temple in Midtown Atlanta.

The only exceptions are matzo or matzo meal, which are flour from any of these five grains and water mixed together and baked in less than 18 minutes under rabbinic supervision, he said. For Ashkenazi Jews, foods that swell -- such as peanuts, rice and corn -- are also prohibited, and that eliminates foods with ingredients such as corn syrup, canola oil or lecithin.

Providing three meals a day for the eight days of Passover can present quite a challenge. Navigating ingredient lists is tricky enough the rest of the year. “Very conscientious people are only going to eat foods that are labeled ‘kosher for Passover.’ They aren’t going to take a risk that something might have contaminated the food,” said Reeves.

The Kroger at the Toco Hill Shopping Center has been working since December to be ready for the holiday. Products that come from as far away as Israel have to be ordered months in advance. By the third week of February, the dry groceries have come in. Frozen foods arrived next, followed by dairy and wine. The store will stock between 1,500 and 2,000 kosher for Passover items.

“We remove everything from the shelves that is not kosher for Passover. By the first week of April, everything on those shelves, in the dairy case and in the frozen food section is something safe to eat during the holiday,” said Gary Libowsky, the store’s manager.

Why the complete turnover of the store shelves? There are four Orthodox synagogues within walking distance of the shopping center at the intersection of LaVista and North Druid Hills roads in DeKalb County. “In addition, we get customers from Florida, Tennessee and North and South Carolina. The whole South comes this way,” said Libowsky.

Each year finds a wider variety of products on the shelves. This season, Libowsky estimates he’ll have about 200 new items, including new juices, new fruit spreads and even gluten-free cake mixes. “I’m Jewish, and growing up your choices of wine were two. Your choices of matzo were limited. We’ve come a long way,” Libowsky said.

Minding what one eats during Passover is just part of the observance of the holiday, but it’s an important part of remembering its deeper meaning.

"The most important element of Passover is that it is our festival of freedom. We were slaves, but now we are free. The matzo that we eat partakes of both because on the one hand, we call it the bread of affliction, reminding us of our time in slavery. But on the other hand, we say that there was not enough time to let it rise because we were rushing to freedom. In that way, eating matzo reminds us both that we were slaves and that God acted to free us in the same bite," said Reeves.

Chag Kasher V'Same'ach. (Wishing you a happy and kosher holiday.)

Recipes

Of all the meals that are eaten during Passover, breakfast might be the one that presents the biggest challenge. Matzo brei is the most traditional Passover breakfast dish, a combination of broken matzo softened in milk or water, then mixed with eggs and pan fried. It’s the breakfast choice of Rabbi Frederick Reeves, who serves his matzo brei with real maple syrup. If you’re ready for a change from matzo brei, here are three different takes on breakfast foods. All of them can be made ahead of time and served cold, or warmed up and served hot. And, of course, they’re delicious freshly prepared. All of these dishes are also delicious served any time of year for breakfast, brunch or even at dinner.

In a medium bowl, mix together 1/2 (half) cup honey, pecans, cranberries, chocolate chips and apple. Set aside.

In a medium bowl using a hand mixer, beat egg whites until when you lift your beater, the egg whites form a stiff peak that holds its shape, about 5 minutes. Set aside.

In another bowl, use the hand mixer to whip the egg yolks, 1/2 (half) cup oil and orange juice until creamy and thick, about 3 minutes. Stir in remaining 3/4 (three-quarter) cup honey, matzo meal and salt.

Use a rubber scraper to fold 1/4 (quarter) of the egg whites into the egg yolk mixture.

Bake for 45 minutes, or until cake starts to pull from sides of pan. Cool 10 minutes; remove cake from pan and cool on wire rack. Serve warm or at room temperature.
