My grandmother's pancakes:

1 Qt. Buttermilk
2 TBS Baking Soda
1 TBS Salt
4 Cups Flour
2 TBS Baking Powder
1 Pkg Dry Yeast
1/4 C. Oil
6 Eggs

Put 1 quart buttermilk in large bowl and add 2 TBS Baking SODA and 1 TBS Salt.

Mix 4 cups of flour with 2 TBS Baking POWDER, stir this mixture into the buttermilk.

Add one package of dry yeast, 1/4 cup oil. Mix.

Whip 6 eggs till foamy, fold in mixture. Do not use electric mixer, use mixer tine by hand.

Pour batter into large pitcher or bowl. Cover with foil.

The next morning put a cup of milk in the pitcher to thin the batter.

Heat pan until hot. Add 3 TBS or so of oil, when water droplets sizzle in the pan it's ready. Cook pancakes in 2s or 3s. When the tops are covered in steam-holes then it's ready to flip. 2 to 3 minutes or so.

Lasts 10 days to 2 weeks in fridge. Yeast will turn black over time, this is normal. Stir batter before use.
