Questions re: Butter extract vs flavoring

[chef koo]

I'm looking to make a lactose free hollandaise. So I'm going with a sabayon, lemon, cayenne, and canola oil. If I want to add a buttery flavor, I'm confused about which one to use...

 

1. Is butter extract super potent? As in a couple drops and you're in butter town?

2. If I had a side by side dish, whether it be with hollandaise, or a cake, or anything, could I taste a significant difference in extract vs flavoring?

3. Is there a major price difference?

Great substitute for butter. Try or don't.

Clarified butter is mostly lactose free since the milk solids are removed.  Do you need it to be 100%?
