If you use the recipe for Dulce de Leche recipe that I posted here, don't use Great Value sweetened condensed milk. It doesn't thicken like the other brands do!
Yesterday, I sent my hubby to the store and he bought the GV brand. I stuck it in the oven and it took forever. I kept checking it, but it was still white. Finally, I stirred it and there was a white liquid layer on top with the caramelized milk on bottom. So I stirred it in with a whisk and baked it a while longer, but it still didn't thicken like it's supposed to. Great Value must add a LOT of water to their sweetened condensed milk! Stick to Eagle's Brand or Carnation. I've used Golden Meadow and it did fine.
Just wanted to let you know!!
