Radicchio salad @ microwave

For ➋
40 g blue cheese
40 g chive oil
25 g hazelnuts, peeled
10 g chives
120 g radicchio, half of a head
olive oil
salt
50 g buttermilk

(Optional: Place blue cheese in the freezer. While this step is purely aesthetic—frozen cheese will curl prettily when it is peeled—the freezer is a good place to store blue cheese so that it's always ready for salads and such.)
Make the chive oil with blanched fresh chives, blend them with oil, strain through a sieve.
Heat oven to 165°C.
Spread hazelnuts on a sheet pan and toast until golden brown, about 30 m.
As the hazelnuts toast, agitate the sheet pan every 5 m for even browning.
Remove hazelnuts from oven and transfer to a large zip-lock bag. Lay the bag flat on a work surface and smooth it so that nuts spread out in an even, single layer. Roll a rolling pin over the bag, repeating until hazelnuts are crushed into small crumbles.
Mince the chives.
Wash radicchio and pat dry with a paper towel. Remove any damaged or wilted outer leaves. Cut radicchio into quarters.
Dress each piece with a generous amount of olive oil.
Place radicchio in microwave-safe dish and cover tightly with plastic wrap.
Cook on high for 40–50 s. Puncture plastic with a knife to allow steam to escape.
Remove from microwave. Radicchio should be warm and wilted, with just a little crunch remaining.
Cut white core from the radicchio and assemble leaves in a serving bowl. Dress with salt, minced chives, buttermilk, and chive oil.

Just before serving, sprinkle hazelnuts over salad and shave or crumble blue cheese on top.
