SOLVED. Simple humorous picture book, brother and sister meet a couple to take them in, brother learns to bake pies, a set of 2 or 3 books with same characters, may have the name "Clyde" in each book's title. [s]

The wife is initially more receptive to the kids than the husband, she teacher the boy to bake pies, the husband comes around because the pies are delicious. Quite short, light. Thanks!

This has to be Joan Lowery Nixon's Claude series:
You Bet Your Britches, Claude!
Beats Me, Claude!
Fat Chance Claude!
If You Say So, Claude!
That's the Spirit, Claude!

I don't remember which one has the pie baking, but it's in one of them.
