Dd is still off cows milk although she is fine with goat/sheep milk and cheese. I want to make her some lasangne and other milky pasta sauces but don't know how to get around the butter (can't find goat's milk butter although I know it exists) in white sauce/cheese sauce. Can I make a roux (sp?) with olive oil? Any non-cows milk mumsnetters out there with a recipe?
