Green pesto is always a real treat! You shouldn’t heat the paste – otherwise the taste could suffer. Green pesto in particular is considered to be particularly susceptible.

Heating green pesto: what exactly happens?

To explain the phenomenon in more detail, you need to take a look at the composition of basil. Like many plants, this contains chlorophyll, which among other things gives the herb its green color.

As the Center for Health writes, chlorophyll is not considered to be particularly heat-resistant. As the scientific magazine Spektrum explains, this is related to polyphenols, which, in combination with enzymes, oxidize under the influence of heat and thus also ensure the characteristic browning of green plants.
