For the Special Sauce, combine the garlic, mayonnaise, capers, brine and lemon juice in a blender or food processor. Zap to roughly blend.
Add the herbs to the bowl with the rest of the ingredients. Zap for a second or two.
Now add ludicrous amounts of black pepper and zap it all until it's all totally smooth and creamy, pausing occasionally to wipe down the sides of the bowl with a spatula so that you get it all in there. The end result should be somewhere between a dressing and a dip.
Taste for salt, adding more capers or caper brine if needed, or pepper or lemon juice, etc. (Sauce will keep in the refrigerator for 4 to 5 days.)
For the Purple Onion Rings, whisk together the flour, salt and black pepper in a large bowl. Like the Special Sauce, this also has to be mad peppery. I just grind until the top looks like black snow.
Now hit it with about 3 tablespoons of hot sauce, then whisk in that seltzer. (You don't want to add flat water, because the bubbles make the batter airier and crispier.) Whisk until you have no lumps and it looks like a pancake-ish batter — when you move the whisk through the batter, you should see ribbons. Whisk in a little more hot sauce until the batter is a nice light pink, like the color of Russian dressing. You won't taste the heat so much, but the rings will fry up a nice golden brown.
Put the batter in the refrigerator for 15 minutes to let it settle a little bit, then line a baking sheet or a plate with paper towels.
Fill a Dutch oven or stockpot with the oil just a little more than halfway up the sides of the pot. Heat the oil over high heat until the oil begins to shimmer. It should be around 400 °F (205 °C) if you have a thermometer, but otherwise you can tell when it is ready because of the shimmer.
While the oil heats, cut the onions into ½-inch (12–mm) thick slices, making sure to separate the rings. It's better to make them a little bigger than a little smaller.
When the oil is hot, dip a few of the rings in the batter with tongs, flipping them once or twice so that they're fully covered. Shake off the excess and then add them to the hot oil just 2 to 3 at a time so they have lots of room to swim.
Flip them with a clean fork when they just begin to turn brown — this should only take a minute or two. Let them cook for another minute or two, until the other side is golden brown, then remove to the paper towels.
Repeat, adjusting the heat of your oil as necessary. Don't let it get too hot or too cool. But since you're only making a few at a time, you're good either way.
Serve these piled high with a side of Special Sauce. Obviously, the cook should keep the Special Sauce nearby the stove and just eat these as they're ready.
