Bitter greens? There’s a fix for that.
Soaking kale in warm water for a brief time can
help reduce its bitterness and make it more
palatable, especially for use in raw salads.
Here's why and how it works:
Why Kale (and other greens) is Bitter:
• The bitterness is due to compounds called isothiocyanates, which are
created when the plant's cell walls are damaged (e.g., by cutting or
chewing).
• These compounds are a natural defense mechanism to deter animals
from eating the plant.
How Warm Water Helps:
• Soaking stemmed and cut kale in hot tap water (around 112°F or
44°C) for about 10 minutes can make the leaves wilt slightly.
• This mild heat helps to activate enzymes that break down cell walls,
leading to a more tender texture and reduced bitterness.
• This process is similar to a very mild form of blanching, which
involves submerging vegetables in boiling water briefly.
• Blanching helps to reduce bitterness by leaching out some of the
water-soluble glucosinolates, which contribute to the bitter taste.
In addition to soaking in warm water, here are other ways to reduce kale's bitterness:
• Massage the kale: Gently massaging the kale leaves with your hands
helps to break down the fibers and tenderize them.
• Remove the stems: The stems are generally tougher and can
contribute to bitterness.
• Add acidic ingredients: Lemon juice or vinegar can help balance out
the bitterness in both raw and cooked kale dishes.
• Pair with sweet or spicy flavors: Sweet or spicy ingredients can help
to mask the strong flavor of bitter kale. Example: Balsamic vinegar
with maple syrup/honey/agave nectar, then a bit of something spicy
like Chili Crisp or your favorite hot sauce.
• Blanching: Submerging kale in boiling water for a short time followed
by an ice bath helps to leach out bitter compounds.
By utilizing these techniques, you can enjoy the nutritional benefits of kale
while minimizing its bitterness!
