So, can you dilute half-and-half to make milk? Absolutely yes. Is it identical to milk? Not really—more like a clever imposter. Think of it as the dairy version of using a spatula when you can’t find a whisk: messy, a little desperate, but surprisingly effective.
The next time you’re staring at a forlorn bowl of cereal and a sad carton of half-and-half, just grab a glass of water and commit. You’ll survive. Your cereal will survive. And you’ll have a funny story to tell at the office about the morning you MacGyvered your breakfast. That’s worth a little dilution.
