In brief
Sticky texture can be a sought effect in a soup, not necessarily a drawback.
Useful to know
Okra secretes a slimy substance that can thicken dishes. Iowa State notes that a stronger cut releases more of it. Therefore, whole pods and very finely chopped okra do not produce the same texture. [1]
If you want thickening of soup, this property may be involved in the recipe. If you prefer more individual pieces, start with a method that is developed for such a result, instead of randomly changing only one step. It is not necessary to present the natural texture as a product failure.
When selected, it looks for tight pods, and for storage, Iowa State recommends a refrigerator and a suitable ventilated package, without pre-washing. [1] Wash the preparation quantity. The size of the cut is part of the culinary solution along with the liquid and the other ingredients.
