I used to use Farmer Peet’s lard for pie crust with any kind of clear soda/pop for the liquid but I cannot find lard anywhere anymore.
Go to a Mexican market. Mexicans never stopped doing a lot of stuff that works when it became not the popular thing to do any more. They pay for stuff cash too.
I use Crisco...
Or just use bacon grease. Do you save your bacon grease? I do and use it for frying eggs and so on. More flavor than butter and healthier than margarine.
You can order it on-line but it's pricey. About 45 bucks for four pounds.
Larousse Gastronomique starts with “first, take a pig” ~ that’s how you start pie.
