Are you missing potatoes? Well it’s time to discover this fantastic vegetable: turnip.

Let’s talk about turnips because oh dear goodness, I really don’t know why I haven’t tried them before. Turnips are a root vegetable that resembles in form, taste, and texture to potatoes.

What Do Turnips Taste Like?

They’re super low in carbs (compared to potatoes) and have a neutral taste.

The taste varies depending on the kind of turnips you can find if they are young or older.

Smaller turnips are tender, sweet, and crunchy. Bigger turnips are spicier and need to be cooked.

At the store, try to choose smaller turnips as the bigger ones have a more of a bitter taste. Select the turnips that have smooth skin and are the size of a tennis ball.
