Sweet Pesto of Mint und Lemon Balm - and Chalkboard Lids!

Hurrah! I have found a very effective way to use my tide of mints and lemon balm from my herb garden, and at the same time, to preserve them in a very tasty way: Pesto! Pesto can also be sweet and makes an excellent contrast to desserts such as panna cotta, crème brûlée, ice-cream, and more or less everything! 
I also tried a new technique for labeling glass jar lids: painting them with chalkboard paint! It is very simple and even dishwasher-proof!





Ingredients for 280 g, about 1-2 glasses:
35 g mint (about 2 handfuls of leaves)
15 g lemon balm (about 1 handful of leaves)

150 ml sunflower oil
2 tablespoons lemon juice
50 g sugar
50 g pine nuts

Preparation :
For the pesto, wash the mint and the lemon balm and pluck the leaves. Then put the leaves in a blender with the lemon juice, oil, sugar and pine nuts, and chop.

Pour the pesto into glasses and cover it with a layer of oil - that way, the pesto keeps for several months.

The practical lid that you can write upon with chalk is made with blackboard paint from the hardware store - it was available in green or black, I opted for black. Clean the lid with some acetone, then paint it with a paint brush. Let it dry well, then try out the chalk and possibly find that some deeper brush scratches are bad for writing, so cover these four lids with a second layer of paint.

Since I like re-using purchased jars of jam, pickles, baby corn, olives, broth, etc., I find the lid-painting very useful, because you can cover a perhaps not too fancy pickles logo! 
Obviously, the chalkboard lids are very practical to mark the changing content of the jar or the filling date! I've gotten the idea from ​​Dani's great DIY Blog and the first painted lids have survived a round in the dishwasher without any problems.
