I was inspired to make this particular potato salad because of an event I attended years ago. I don't remember the details of each flavor profile but the ones that stood out were reimagined as you see here. This is the type of dish that needs a little extra time to marinate. Go ahead and plan out your day and the rest of your accompaniments with the potato salad in mind. What I mean by that is simply make sure you set aside a couple hours so that it can sit in the fridge. This will give all of the flavors a chance to really blossom.
The ingredients are specific
This recipe calls for the use of black truffle oil extra virgin olive oil, arugula, and mustard seed, they all play a major part in the way this potato salad tastes. Additionally, either sea salt or kosher salt is best. Both of these will distribute in a similar way-you'll get little chunks of salt that show up in tiny bursts. The use of grated garlic is key here. Raw garlic has a very strong taste and I wanted the garlicky flavor to be more delicately laced throughout.
Mustard seed, to crush or not to crush...
One of the most important elements of this dish is the use of mustard seed. It brings so much flavor and really diversifies the flavor profile. There are a couple of different ways to achieve these results that will give you two different effects. The first way is to simply add in the mustard seed as it comes. If you do it this way, as you're eating you will get little bursts of mustard flavor that are dispersed randomly when chewing. The other option is crushing the mustard seed with a mortar and pestle. With the second method, you will get more mustard flavor spread throughout the potatoes. If you're indecisive about which method to choose, try mixing your potato salad together completely first before sampling some with a fork. Add a few unground mustard seeds to your forkful of potato salad and see if you like this version.
How to get the potatoes just right
When making potato salad, you'll want to follow a few very important steps. First off, make sure that your potatoes are cubed as evenly as possible. This will ensure that all of the potato pieces cook through, together. For the amount of potatoes mentioned, you'll need to grab a medium-sized pot. If doubling or even tripling this recipe make sure your pot can easily fit all of the potatoes plus enough water needed to cover them. Fill the pot ¾ of the way with water and make sure the water is at a rolling boil before carefully adding in the potatoes.
For the amount of potatoes mentioned, boil them for 12 to 14 minutes. After this time, they should be fork-tender meaning you can easily poke a fork through each piece. Be cautious of the cooking time because once you drain the potatoes from the water using a colander, they will continue to cook slowly. The goal is to cook them just enough so that they're tender but not too much to the point where they're falling apart.
A super simple process
The process of making this potato salad really is rather simple, all there is to do is cook the potatoes and combine all of the ingredients together until everything is incorporated. For the best results, let it "marinate" for a couple of hours in the fridge before preparing to serve. You can leave it out at room temperature for about 20 minutes or so right before you get ready to eat, just to take the chill off.Print
