I do. I believe you get different results using it, rather than chopping (or mashing, etc.) for every dish you make.
For instance, my SIL loves my tzatziki. I told her how I made it.......and several times she has made it, she says "it never tastes like yours". After many attempts, I found out that she didn't use a garlic press, she chopped her garlic. I tell her, that's the key - to use a press. I even went out and bought her one. She must've thrown it out b/c I can't find it in her kitchen anymore.
She swears there's no need to use one at any time. I do. Thoughts?
