Step 1

Start a large pan of water boiling for your ravioli.

Step 2

Meanwhile, get to work on your sauce. Melt the butter in a small saucepan over a low-medium heat. Add the sage leaves and allow to cook until they are shrivelling and getting crisp. (You can cook until the butter is fully browned if you wish, but I personally don't go any further once the sage is a little bit crisp.)

Step 3

Remove from the heat, add the lime zest and juice, and then set aside.

Step 4

Once the water is boiling, add the ravioli and cook according to package instructions. Once ready, use a slotted spoon to scoop it out onto plates for serving.

Step 5

Pour butter sauce over the ravioli, sprinkle with cheese and pistachios, and serve!
