Roasted Potatoes and Asparagus with Homemade Mayo

There are certain friends you can do anything with. That’s how it is with me and Jenn- she can always text me with some random suggestion and I’m always up for it, and vice versa. We’ve taken cake decorating classes together, done crafts, and both find it helpful to plot out stores to visit in malls before we actually go shopping. 

One afternoon where we were both off from work, she decided we needed to try making mayo from scratch. Not something I had ever considered before, and definitely not a phone call I’d get from everyone, but sure, why not? 

We used the food processor and after wasting 2 cups of oil, gave up. But Jenn got it right later on, and raved about how good it was. 

Months later, I decided to finally try it out on my own. It was so simple- 1 egg yolk, 1 cup of oil, salt, and a whisk-induced arm workout.  The mayo was delicious, with a lighter texture than the bottled stuff and a more delicate flavor from the olive oil.

I took the liberty of flavoring my mayo with lemon, parsley, and capers, and I used it as a topping for roasted potatoes and asparagus. It was sooo good. This is perfect dinner party fare, or would make a delicious side for a spring holiday meal. 

Roasted Potatoes and Asparagus with Homemade Caper Mayo

Serves 4-6 as a side dish

2 lbs fingerling potatoes (I used a mixed color variety bag)

1 bundle fresh asparagus

Olive oil

Flaky sea salt

Freshly ground pepper

Preheat oven to 425 and line an aluminum sheet pan with foil. 

Slice potatoes in half or in quarters if very large. Drizzle with olive oil, add salt and pepper to taste.  Place on sheet pan and roast for 35 minutes.

While potatoes cook, prepare asparagus. Snap them at the ends to remove the woody part of the stems, and then cut the spears into 2 inch lengths.

At 35 minutes, add asparagus to pan with potatoes and roast another 10 minutes. 

Place on serving platter and dollop with mayo, recipe follows. 

For the mayo, basic recipe from The Art of Simple Food by Alice Waters:

1 egg yolk

1/2 tsp water

1 cup mild olive oil

1 tbsp lemon juice 
Pinch of salt

Caper Parsley Flavoring:
1 tbsp capers

¼ cup flat leaf parsley leaves

½ tsp grated garlic (you can use more, I just don’t love an intense garlic flavor)

Additional lemon juice to taste

Flaky sea salt and pepper to taste

Whisk together egg yolk and water in a small bowl. Add the oil in tiny drips, whisking constantly. You have to add it very, very slowly in order to create the emulsion. It is annoying, but go drop by drop at first.  After a minute or two, you will see everything start to thicken up and an emulsion form. Once that happens, you can add the oil a little faster, in a slow stream.  Keep whisking constantly; the process will take about 5 minutes. (Not actually that long, but it feels long!)

Once your mayo’s done, you can add the flavors. Chop together your parsley and capers. Add to mayo along with garlic. Taste, and add salt, pepper, and additional lemon juice as desired. Can be made ahead. Flavors will intensify as it sits; mayo will last about a week in fridge.

Experiment with this- try adding different herbs, spices, etc. You can create chipotle mayos, smoky mayos, arugula mayos- have fun!
