Legumes: Soaking and Rehydration

Hi! I'm Elena, your nutrition expert from Castelló, and today we're going to dive into two basic techniques with a lot of science behind them: soaking and rehydration.

This morning, while I was soaking some chickpeas here in my Novelda kitchen, I was thinking about how important this preliminary step is. It's not just "wetting" the food; it's an osmosis process in which dried legumes, mushrooms, or fish absorb their constitution water again, increase in volume, and, technically, transform their structure so we can digest them better.

Soaking: Much more than just increasing volume

Legumes (lentils, chickpeas, beans) are dry seeds that need to "wake up." Prolonged soaking, usually overnight, not only reduces cooking time, but also triggers vital chemical changes:

• Goodbye to gas: During soaking, oligosaccharides such as raffinose (the culprits behind gas) dissolve in the water. That's why it's so important to discard the soaking water and use fresh water for cooking!

• Removal of anti-nutrients: Enzyme inhibitors such as trypsin are diluted, which dramatically improves protein absorption.

• The pH trick: If you live in an area with hard water (high in limescale), legumes can stay hard because calcium binds to the skin.

  • Technical tip: Adding a pinch of sodium bicarbonate to the soaking water helps keep cell walls from hardening.

Sprouting: Nutrition in Progress

If we leave the legume soaking longer than needed, sprouting begins. This process turns the seed into a "seedling" and its nutritional benefits skyrocket:

• Maximum vitamins: In just 72 hours, soy vitamin A can increase by 370%. In wheat, vitamin C can rise by up to 600% in the first few days.

• Total digestibility: Proteins break down into amino acids and carbohydrates into simple sugars, making sprouts light and highly nutritious.

• Chlorophyll: Green sprouts provide chlorophyll, a powerful regenerator that helps oxygenate our cells.

Tools from My Pantry

To make your legume dishes or sprout salads complete and healthy, balancing flavor is essential.

• Refreshing touch: If you're making sprout salads or cold legume salads, try pairing them with our Iced Tea Lemon.

  • It has 0 sugars and it's the perfect drink for a light, nutritious meal.

Elena's "Life Tip"

Rice and Potatoes: Don't reserve soaking just for legumes. Rinsing Basmati rice several times until the water runs clear removes surface starch, leaving the grains loose and perfect. The same goes for potatoes cut before boiling or frying; that short soak makes all the difference between an average result and a professional one.

Are you the kind of people who always forget to soak the legumes the night before, or do you already have your system organized? Tell me your kitchen tricks!
