MASHED POTATO BUTTER AIOLI W/ FRIED CAPERS

[ezcol_1third] IS IT MASHED POTATO, OR IS IT A SAUCE?  IT'S THE BEST OF TWO WORLDS. [/ezcol_1third] [ezcol_2third_end] In the past few days, I don't know if you can tell, but my year-long travel-ban situation (recap: sick soupy Dumpling has been losing his juice) has advanced to some sorta voluntary house-arrest, and besides spending all my time migrating him in between the bed and the bathroom, I'm also doing everything I can to not make it too obvious, that I'm trying to live out of a single potato. And now I'm doing it again.  Guess I gave up. But really though, am I the only one fascinated?  I mean, what's the one thing most feared, about an aioli or butter sauce?  No, not that it'll grow you an extra thigh, which it will and that's that.  But it's actually, with radical willingness, that both itself and your heart, it'll sadly break (so true, Yoda.  so true).  Which is what makes this recipe, a hybrid between mashed potato and butter aioli, so superbly amateur-friendly.  We all know how the line between a "side-dish" and a "condiment" goes increasingly blurry for the most creamy and buttery "mashed potato" of its kind.  So why not smudge the line even further?  A smooth and silky butter aioli
