Homemade Onion Dip

3 onions(1 white, 1 sweet yellow, 1 red) finely minced.
I actually run mine through a meat grinder and squeeze out the liquid to get an even better texture. 

Slowly caramelize in 2 Tbps of butter over Medium-Low heat for about an hour, add salt, pepper, Caraway seed, thyme, and chili flake halfway through.

 Once caramelized allow to cool.
 Mix 1 cup each of Mayo, Plain Greek Yogurt and Sour Cream with 1/2 cup buttermilk.
 Add another round of S and P and a bit of celery seed. Allow to sit at least 8 hours before serving
