I followed this recipe and the advice from this article. You should try it!
(The sauce goes on the nearly twelve dozen chai-spice profiteroles I made for Seekrit Satan tomorrow. I make 'em small, so a double recipe of choux paste makes a LOT.)
Also, the Sunbeam Mixmaster stand mixer that my Mom passed on to us when they sold the house, which is probably from the '60s or '70s? Is AWESOME. I love this mixer. It has a very simple, low-tech design that works REALLY well. Sometimes old is good.
