The ideal firmness for sweet potatoes depends on the intended use. If you plan to bake them, then a firmer sweet potato is better. This will ensure that it retains its shape and doesn’t become mushy during baking. On the other hand, if you plan to mash or puree the sweet potatoes, then a softer one is better. The softer texture will make it easier to mash or puree and result in a smoother consistency. When selecting sweet potatoes from the store, look for ones that are free from bruises or blemishes and have smooth skin. If you press into them lightly with your finger, they should feel firm but not rock hard. Avoid any that are soft or spongy as this could indicate they are rotting inside.
