This is just a reminder for myself. Removing leaven for the Feast of Unleavened Bread has become a lot easier than it was when we first began observing YHWH's feasts because in the beginning, we didn't understand what "leavened bread" really meant. Here are the guidelines we currently follow in our home:
1. We put out all bread products that have yeast, baking soda, baking powder or sour dough in them. We do not throw out baking soda or baking powder though.
2. Beer and grain alcohol are also fermented grains so these would be put out as well. Some might also put out distilled white vinegar and soy sauce.
3. We do not put out pasta as it does not contain leavening agents.
4. Kefir grains do not need to be thrown out as they are not used to ferment grains. Yogurt would also be fine to be kept in the house.
5. Wine is also fermented but it is not a grain, thus acceptable to consume and keep in the home over the feast.
6. We also do not put out items that might contain autolyzed yeast (like canned soups, etc). It is a dead yeast and is only used for flavoring. It will not leaven because it's dead. (Since we have limited processed foods in our diet, we have little if any of these things in our home now.)
It is important to remember that this is the Feast of Unleavened Bread (bread is a grain product) so we want to remove grains that have come into contact with leavening agents. So, it's pretty simple now for us to understand what will have to be removed.
Exo 12:19 Seven days shall there be no leaven found in your houses: for whosoever eateth that which is leavened, even that soul shall be cut off from the congregation of Israel, whether he be a stranger, or born in the land.
