Lemon sounds good.
My Mom did a fabulous lemon dessert ...... no baking required.
She'd layer in an oblong pan whole sheets of grahams (not crumbs) and lemon pudding.
Crumbs came at the top as a garnish.
Then it was chilled....the chilling turned the Grahams into a cake-like layer.
I've served it.....people never guess they're eating graham crackers.
