I've been drinking Passover Coke for quite some time now, although I don't think the difference is something to shout about. I love beer, and I love pizza, but I find the combination of beer and pizza disgusting. And when someone else at the table drinks beer, they will inevitably deliver a Budmilcoors-and-pizza belch that smells so bad everyone else will want to heave. Give me Coke, every time.
RE old-style McDonald's fries, one of the recipes in my cookbook is for twice-fried fries made in beef fat. They are unbelievable. Duck and goose fat are said to be even better.
McDonald's fries are garbage now. I don't know of a single restaurant that makes fries correctly. The other day I tried Five Guys fries, and while everyone raves about them, they were just big fries cooked in what tasted like canola oil. Not great. Canola either tastes like nothing or fish, depending on the batch.
The local groceries here give me free beef fat. I ask them to save it, and then I cart it out. Once I ordered a Noche Buena pig and also asked for beef fat. When I went to pick up the pig, they had two huge packages of fat waiting, and I rolled the pig and the fat out past the other shoppers on a utility cart.
