Why is okra slippery when heated?

Okra becomes slippery when heated due to the presence of mucilage, a gelatinous substance found in its pods. When cooked, the heat causes the mucilage to be released, creating a viscous texture. This characteristic is often desirable in dishes like gumbo, as it helps to thicken soups and stews while adding a unique mouthfeel. The slippery quality also enhances the overall richness of the dish.
