I process pumpkin, and nearly anything else, using a very old woooden-handled potato masher which has a working surface consisting of a 4" round metal plate containing rows of 1/4" square holes.

I mash coarsely for fruits or vegetables used in quick breads or muffins to give them some texture, about medium for a pie filling som it has some body, and quite thoroughly for something like a pudding or cheesecake filling.

I often use the same tool for miking wet ingredients together.

I like the control which hand tools offer.
