Finely chop all of the herbs and green onion. Discard herb stems and only use leaves/flowers.
Add softened butter, herbs and onion to a mixing bowl and whip until thick and creamy using electric beaters or a stand mixer (see notes for equipment).If using a Thermomix, you do not have to chop the herbs first.
Notes
Notes on EquipmentYou can use electric beaters or a stand mixer for this recipe. A Thermomix is perfect too as you don't have to chop the herbs first.If you do not have either of these, just mash the herbs into the butter using a fork. Using a fork will not give you the whipped texture, but you will still get the same flavor.Notes on MeasurementsI have chosen to express the herbs using spoons rather than grams. While you know I much prefer measuring in weight, it was really hard to weigh the herbs with my kitchen scale. The measurements for this recipe do not have to be exact, so the spoons are fine for this one.
