Some advice for the person who added 7 tsp. cornstarch.. Cornstarch only thickens when it comes to a boil so that's probably what the problem was.
Very easy and ingredients are usually on hand. Good taste but I added 7 tsp. of cornstarch and it was still very thin. I made it to go on cinnamon bread pudding. Very tasty. Will make again ...
I had chunks of cornstarch when I made it so I had to strain out the cornstarch.
