So I decided to do the chiffonade of spinach!! It's kind of a fun technique with a very fluid motion. Chiffonade is a French word meaning "rags". Basically, what you're doing is turning a leafy green vegetable until fabric-like strips.
For this technique, the French chef's knife is probably the best bet, and i'll explain why later on. Take your spinach, rinse the leaves and dry them with a paper towel. They need to be very dry before you begin.
Next, stack them into a pile of six leaves, bigger ones on the bottom, veins all lined up.
Then, roll them into a semi-tight roll, but not so tight that they break apart.
Then, keeping the knife up agaist your middle finger, slice off very small strips, always keeping the knife on the board, using a lot of motion in your wrist. This is where the French chef's knife is especially useful because it is curved toward the tip, making this considerably easier.
You don't want to chop it, you want to slice it, so start with the point of the knife down, handle up, and slide the knife forward slicing through the spinach very quickly.
The spinach make a very satisfying squeak when you cut it right.
Continue to cut the leaves, moving your fingers back in increments.
When you're finished, the spinach should remain very dry. If you have to saw at it or put too much pressure to cut it, the spinach will start to bleed and become wet.
This technique works for pretty much any leafy green vegetable. I have done basil this way, chard, maybe even kale. This is very good for salads because the dryness of the spinach will then be able to absorb a lot of moisture from your fat source (dressing). This is also really good in soups, maintaining a small size so as not to overwhelm other ingredients. I boiled some penne, added pesto, the spinach, one piece of bacon chopped up, parmesan, and seasoned to taste and had a nice derivation of pesto.
