We been eating it ,using pork fat, at 70/30 but it’s fairly lean . I been thing of bumping my fat up to 40%. Luckily I can get pork fat at my local Brookshires grocery store.
Here locally people get together and have a tamale making party as it helps a lot to have multiple hands involved. last year we did one and made all pork some with spice some not. It is lots of work, but yummy
