Ketchup leather is air-dried ketchup that has been spread out thinly.
The ketchup must be dried first. Ideally, spread it out on a baking sheet lined with a baking mat. If you don’t have a baking mat, you can use normal baking paper. However, this is not quite optimal, as it creases during drying and the ketchup leather becomes somewhat wavy. It’s not really bad, but it doesn’t look that nice.
Spread the ketchup evenly on the baking sheet with a spatula. The ketchup mass should not be too thick (about 2 mm is ideal), otherwise, it will take a long time to dry. At around 60 degrees, the ketchup leather now has to dry for around 3-4 hours. It’s ready when you run your finger over it and the ketchup is no longer wet or sticky.
You can use the leather on burgers or sandwiches – it tastes intense and tomato.
