Title. I'm lactose-intolerant and try to veganise.
I also love cortado but only had it in cafes in Spain.
Is it possible to make cortado at home with a plant-based milk and if yes - how?
Yeah!! My fav is oat, but any non-dairy milk will do. You might want to test the milk with your espresso, as the acidity may curdle your plant milk. Soy commonly curdles with drip coffee.
There is a "barista" style oat milk that does great with steaming. Wish I could remember the brand, but it's in the US if you're there and works really well.
The majority of oat milk brands also produce a "cafe" or "barista" version. These should be available in the grocery store but if not, select an "extra creamy" labeled oat milk.
For anyone curious, the difference with these barista versions is that they have added proteins, fats, and/or emulsifiers that help create a more consistent foam.
