Of course you do! Duh!
And I am here to tell you that if you have never made your own croquettes before, its easier than you think!
Buy the best ones you can find- it does make a difference, and don’t substitute regular white mushrooms because their flavour just isn’t strong enough to carry the recipe. You could probably sub a good quality batch of chestnut mushrooms without losing too much, though.
By taking care with each step, you will get a nice crisp outer coating and creamy, oozing middle. So long as you get the bechamel thick enough and coat each croquette perfectly, I find that you can’t go wrong.
Let me show you!
