Butter rules

Notes to self:

For yeast dough, put the butter in when you start the second stage. Later, and it won't bind well. Kneading by hand will fix it after a while.

For shortcrust, use cold or soft butter.

For crumble, use very cold butter in thin slices, or it will become shortcrust.

Pay attention when baking. It's not a forgiving craft.
