I've made some that ALSO has butter. REC: cottage cheese pastry. Do you want to sub different fat,
or to reduce the fat? If you're concerned with cholesterol but not fat, I've had success substituting Smart Balance for some of the butter, or substituting canola oil for some of the butter.
To reduce the amount of butter used in a sauteed dish, saute in canola oil, and add a little melted butter at the end for flavor.
Cottage Cheese Pastry
2 cups flour
1 cup cold butter or margarine
1 cup cream-style cottage cheese
Cut butter into flour (or pulse in a food processor). Mix in cottage cheese with a fork until just combined. Gather into a ball, cover with plastic wrap, and chill until ready to use.
This will make about enough for a covered pie, though I always use it for turnovers.
