Pasture Butter or KerryGold. I just bought this set of two at Tuesday Morning for $9.99. I would have bought three more, but this was the last one at that location. It's made by Fifth Avenue Crystal. It's the Portico design, and it matches the punch bowl that Nathaniel gave me for Christmas one year. If I don't find three more at another Tuesday Morning location, I'll hunt them down online!
Of course, these are kind of fancy. For everyday use, I found a clear glass one and a white porcelain one at Crate and Barrel for $4.95 each. They are next on my procurement list. I think I will go with the clear glass, because my dishes are an off-white. Plus, if you're like me and use butter from grass fed cows, you get to see the gorgeous deep yellow of the butter with the glass one. It's like having a sunny day right on your table. . .hmmm. I just had a vision of two of our eggs with their almost-orange yolks, sunny side up on a plate with my little crystal butter dish alongside. I think this detox/elimination diet is finally getting to me. I haven't had any eggs or dairy in a couple of weeks.
