Three Sisters Soup (corn, beans, and squash)

The "Three Sisters Soup" is a traditional recipe inspired by Native American cultures, particularly the Iroquois tribes. It gets its name from the three main ingredients - corn, beans, and squash - which were grown together using an agricultural technique called the "Three Sisters". This method allowed the plants to support each other and enrich the soil, creating a nutritious and sustainable foundation. "Blue Zones" are regions of the world where people live longer and healthier lives. Research has shown that these communities share similar dietary habits, including a high consumption of vegetables, legumes, and whole grains. The Three Sisters Soup, with its main ingredients of corn, beans, and squash, aligns perfectly with this type of diet. By enjoying this soup, you embrace an ancient culinary tradition while supporting longevity and vitality, reflecting the dietary habits of Blue Zones.

    Simple yet delicious dish. Even on the plate, the three vegetables complement each other as they do in the fields, bringing taste and texture. I will definitely make it again without hesitation.
