I got a tube of condensed milk sitting in my fridge idk what to do with it, any recipe suggestions are welcomed.
Sweetened condensed milk can be simmered overnight, in water, in a slow cooker, in its unopened can, and the heat slowly caramelizes the sugars into a rich sauce. This is called
'dolce de leche', you probably had it before in ice cream, and I am not sure if it's Italian or Spanish. But it tastes great on a lot of things! Bread, ice cream, yogurt, fruit, cake, idk, add it to your cereal. Glaze a city ham with it. I'm quite sure that would taste fine.
It's a key ingredient (no pun intended) in key lime pie, provided you have enough. You can make that pie with regular limes, btw.
Other uses: if you take your coffee light and sweet you can use sweetened condensed milk to achieve this if you don't have fresh milk on hand. I did that a lot during the pandemic. The shelf stability is probably why it's heavily associated with Vietnamese coffee drinks.
One of the leches in tres leches cake is sweetened condensed milk, this is likely more trouble than it's worth for you.
In Latin America I think it's often served with fresh fruit as a kind of berries n cream quick dessert. Worthy of consideration.
Checking the web I see it's often used in puddings and trifles (layered desserts that are usually cake and a type of pudding, optionally fruit/jam)
APPARENTLY its in coconut macaroons, who knew. (Not me I ain't eaten those for ten years - which is when I gave up Judaism and having to eat these macaroons as a kosher-for-Passover dessert. No regrets, at least not with regards to the macaroons.)
