Common Questions
Is this true sweetened condensed milk?
Not exactly. This is a quick homemade condensed milk style substitute. Classic sweetened condensed milk is milk that is reduced and concentrated for longer. Here we get a similar sweet, spoonable feel with a short simmer and a little cornstarch, so you can have a jar in the fridge without hovering over the stove forever.
Will it thicken like the canned kind?
It gets very close. You are looking for a texture that ribbons off the whisk and briefly holds a line on the surface before melting back in. If you like numbers, aim for about 215°F / 102°C at a gentle simmer.
Can I make it without cornstarch?
Yes. Just simmer longer over low heat and stir often. Expect it to take an extra 6 to 12 minutes, and it may end up slightly thinner than the canned version.
Is 1 tablespoon cornstarch too much?
It works, but it needs a real simmer to cook out any starchy taste. Keep it gently simmering for 3 to 5 minutes after adding the slurry. If you prefer a lighter body, start with 2 teaspoons cornstarch and use the same method. You can always add the last teaspoon if it is not thick enough.
How sweet is it?
It is still sweet, just less intensely sweet than the canned stuff, especially with the citrus and berries balancing it. If you want it less sweet, reduce the granulated sugar by 2 to 4 tablespoons. The final sauce will be slightly thinner.
What fruit works best?
Strawberry and raspberry are my favorites for “fruity and bright.” Mango is great too, but it reads more tropical. This recipe uses jam (or powder), which is ideal because it is concentrated. If you decide to experiment with fresh fruit purée, avoid very watery fruits because they can dilute the dairy and loosen the texture.
Can I use honey or maple syrup instead of sugar?
You can, but it will change the flavor and thickening. Start by swapping only half the sugar with honey or maple, then adjust from there. It can also brown faster, so keep the heat gentle.
Does the citrus curdle the milk?
It can if you add a lot of juice while the mixture is very hot. That is why this recipe uses mostly zest for brightness, plus a small amount of juice stirred in off heat after a short cool down.
Whole milk vs half and half?
Half and half gives a little more body and a smoother, richer finish. Whole milk works too, just expect it to be a touch lighter and slightly less lush.
