The oil-roasted fish was nothing to write home about, but with the accoutrements, it didn’t really matter. What made me grumpy is that Alison has you use a whole head of garlic and several sprigs of thyme that never really make their presence known in the fish. She has you cut the garlic head in half lengthwise and put it and the thyme in the pan with the sardines (trout) while they roast, but they only bake for 15-20 minutes. This wasn’t long enough for the garlic to be really roasted (and thus edible as a side), and the garlic and thyme didn’t make enough contact with the oil for it to serve as a useful conduit for the flavors. I wondered why she didn’t have you smash several cloves of garlic and scatter them around the pan, or even give them a head start in the oil in a saucepan before roasting. The skin on my trout also didn’t get very crispy with her method, but that might have been different with sardines.
Now about the mayo: this is aioli. They are the same thing, but if your goal is to make a “mayo for people who don’t like mayo,” you bypass so many obstacles by calling it “aioli.” But whatever you call it, it’s a little tricky! There was a span of a few weeks early in high school when I encountered several recipes for mayo or aioli that came with a disclaimer of “people think this is hard, but my method is foolproof!” (Often said about making mayo in a blender.) Yeah, OK. They were not foolproof. But this mayo went just fine! She has you use two egg yolks, which is more than you need for this amount of oil, but I described it to Annie over the phone as an insurance policy.
Let’s take a detour for a primer on emulsions! Mayo, aioli, creamy salad dressings, and many other sauces are emulsions. This just means it’s a homogeneous mixture of oil and water. In order to get oil and water to combine and not separate, you need an emulsifier (like an egg yolk) to serve as a mediator between oil and water and help them get along. In making mayo, you start with an egg yolk, often with a little mustard and some lemon juice, and very gradually whisk in oil. The first time I made it successfully, I got my station set up, called my friend Amy, and put her on speaker so I could have both hands free for drizzling and whisking. I was so paranoid about going too fast with the oil integration that I paced it out over the course of a whole hour. This time, I called Annie and did it in about 15 minutes. This is growth!
Last thoughts on aioli: it’s tough to gauge seasoning on a condiment. I tasted the aioli on its own a few times and kept wanting more acid and more salt, so I added them, and I’m glad I did. But when I put the aioli in the fridge for a bit while I worked on the other dishes, I wasn’t convinced it was going to have enough spunk. It’s just so unctuous! It’s hard to ever taste it and say, “I want a big spoonful of that in my mouth NOW.” So, if you make aioli, go farther than you think you should on acid and salt, but also bear in mind what it will accompany. The lemon slices and pickled onions did a lot of work here in balancing out the creamy aioli, but if I were serving it with something less zippy, I would want the aioli to be more assertive.
