Potato & rocket salad with toasted walnuts FAQ:

What is the best way to store leftover potato salad?

Store leftover potato salad in an airtight container in the refrigerator for up to 3 days. For best texture, avoid freezing as the potatoes may become mushy.

How do I know when the potatoes are done cooking?

The potatoes are done when they are fork-tender, meaning you can easily pierce them with a fork. This usually takes about 10-15 minutes of simmering.

Can I substitute any ingredients in this salad?

Yes, you can substitute Greek yogurt for sour cream, and you can use any type of vinegar if you don’t have the specific one called for. You can also replace walnuts with sunflower seeds or almonds if preferred.

What pan size is needed for toasting the walnuts?

A standard baking sheet (around 13x18 inches) works well for toasting the walnuts. Make sure not to overcrowd the nuts for even toasting.

Is arugula the only green that works in this salad?

While arugula provides a peppery flavor, you can substitute with baby spinach, mixed greens, or frisée for a milder taste.

Tips:

- Choose waxy potatoes like Yukon Gold or red potatoes for the salad as they hold their shape better after cooking.

- Toast the walnuts in a dry skillet over medium heat for 3-5 minutes, stirring frequently, until they are aromatic and lightly browned.

- For a creamier texture, you can substitute Greek yogurt for sour cream.

- Chill the salad in the refrigerator for at least an hour before serving to allow the flavors to meld together.

- If you prefer a stronger flavor, add an extra tablespoon of mustard.
