So, radishes. People have STRONG opinions about them. Like really, really, really strong opinions. I'm one of them. For the most part, I avoid them. There's story there. It involves me sitting on a swing at my grandparents' forcing down a honking big white radish that had been "polished" clean on my grandfather's work jeans. Why was eating said root vegetable if I didn't like it? Well ... my grandfather already had opinions about my pickiness where vegetables were concerned so I wanted to prove that I wasn't THAT picky about veggies and could eat a radish like an apple, flecks of dirt and all. It should be noted that I didn't eat the whole radish.
I was SCARRED and thus avoided the radish for the next almost twenty years or so. When I make up my mind that I don't like something, I tend to stick to my guns. Until the day that I don't. Which, if you hadn't guessed, is exactly what happened with radishes ... but only so in far as putting them on pizza is concerned. I still don't think I could eat them raw. *shudders*
So, radishes on pizza - it's a thing, and it is GLORIOUS. There's something that occurs in the oven to a paper-thin slice of radish that increases it's spiciness and creates this delicate flash of not-quite-pepperiness when one takes a bite of it. Pair that with the sweetness of the apple, the not-so-delicate (and completely different) fresh pepperiness of the rocket pesto (arugula isn't nearly as fun to say as rocket), the heat from the sausage, and the nuttiness from the shaved parmesan and you have one beautiful flavor party going on.
I can hear you, by the way, raging at me that radish (and possibly apples) don't belong on a pizza. To that I say: expand your mind and your palate. TRUST.
Note: to make rocket pesto place one cup tightly packed rocket into a food processor with 2 TBSP olive oil, 1 minced clove of garlic, and 1/2 tsp kosher salt. Pulse until smooth.
Rocket Pesto, Sausage, Apple, & Radish Pizza
1/2 recipe of Beer & Ground Oat Pizza Dough
2 Trader Joe's Spicy Italian Vino & Formaggio Chicken Sausage; cooked and crumbled
1/2 pink lady apple; sliced paper-thin
2 -3 red radishes; sliced paper-thin
1 recipe rocket pesto (see above)
1 ball fresh mozzarella
Preheat oven to 400º (if you use a pizza stone make sure it's in there).
Make sure there's corn meal on the hot pizza stone, then you'll PAR-BAKE the pizza dough with a thin layer of rocket pesto on it for 5-7 minutes ('cause weepy pizza crusts are gross).
Remove from oven, add another thin layer of pesto sauce, and then start assembling your pizza! I put the apple slices down first, next up: sausage crumbles, then I tucked the radish slices in and around everything else, finally top with fresh mozzarella slices (I use a "flower" pattern, on in the center and the four to five - depending on the size of the pizza - around the outside as petals).
Bake for 20 minutes or so. The crust should be nice and golden and the mozzarella might have a few glorious brown spots as well.
Top with shaved parmesan, slice and serve.
