LOL, here's the whole thing with the other side of the card included:
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.
(don't confuse the soda with the powder, it will taste weird)
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 (may cook faster, watch that they don't burn).
Lasts 10 days to 2 weeks in fridge. Yeast will turn black over time, this is normal. Stir batter before use.
