Pasta with Caramelised Cabbage, Sage and Walnuts

1/2 head of Savoy cabbage
120g unsalted butter, divided
2 tbs extra virgin olive oil, divided
3 garlic cloves, finely chopped
1 sprig thyme
15 fresh sage leaves, divided (leave 10 sage leaves whole; cut the remaining 5 leaves into thin shreds)
60g unsalted walnuts
250 grams dried pasta (I used Casareccia, a short pasta similar to penne), roughly half a package of pasta
1 handful Parmigiano-Reggiano cheese to finish

Fill large saucepan with water and bring to a boil over high heat. When boiling, turn down the heat a little and add salt until you have a saucepan of water as salty as the sea.

While water is coming to a boil, remove core from cabbage and slice into 2-3 wedges. After water is salted, add cabbage wedges to boiling water, cover pot and blanche for 3 minutes. Remove cabbage wedges from pot and add to large bowl filled with a mixture of ice water and ice. Reserve the hot blanching water. When cabbage has cooled, remove from ice and ice water mixture, dry thoroughly with some tea towels, and cut into 1 inch pieces.

Bring blanching water back to a boil. Preheat oven to 325 degrees. After cabbage has cooled, add 1 ounce butter and 1 1/2 tablespoons olive oil to large frying pan. Turn heat on to medium low. When oil is warm, butter has melted and is a lovely golden colour, add cabbage slices to pan in single layer, if possible. Cabbage may splatter if it is still slightly wet. If that happens, turn heat down a bit. Let cabbage cook for about five minutes without disturbing until underside is caramelized. Watch it carefully because you don't want it to burn. It should be a lovely golden colour, not blackened. When cabbage has caramelized on one side, carefully turn pieces over and continue to cook. You may have to adjust the heat, if necessary. You don't want the pieces to cook too quickly. Aim for about five minutes per side.

While cabbage is cooking, add walnuts to a baking dish and place in preheated oven. After about five minutes, check on the nuts. If they are starting to smell fragrant and are a beautiful golden colour, remove from heat. Otherwise, give them another minute or two to finish toasting. Remove from heat. Crumble nuts if pieces look too large. Add remaining 1/2 tablespoon (you may need less) olive oil to nuts, just to very lightly moisten them. Sprinkle with sea salt and reserve.

After the cabbage has been cooking for about five minutes, start cooking your pasta. When blanching water has come to a rolling boil, add pasta. Keep water at a steady boil, adjusting heat if necessary. Give pasta a good stir with a ladle to make sure pasta is not sticking together.

Once cabbage is caramelized on all sides and is a lovely golden color, add garlic to pan. When you can smell garlic cooking (after about 1 minute), add thyme sprig and chopped sage leaves to pan. Add a ladleful or two of pasta water to pan, lower the heat and keep at a simmer while pasta finishes cooking and while you prepare the brown butter.

Add 3 ounces of butter to small skillet. Turn heat on burner to medium. Once butter has melted and is a lovely golden colour, add 10 whole sage leaves to pan. Turn heat down to medium-low. Stir butter frequently, spooning butter over sage leaves. Watch carefully, you don't want the sage leaves (or the butter) to burn. After about 5 minutes, when sage leaves are a slightly darker green and are no longer limp, remove from butter with slotted spoon. They should have a nice crisp texture. If not, return to butter to continue cooking for another minute or two. When sage leaves have crisped, drain on paper towel-lined plate. Continue cooking butter until it is a lovely dark brown colour, about another minute or two more. Remove butter from heat.

When pasta is almost finished cooking and is still a bit al dente (taste it, if you are in doubt), fish pasta out of saucepan with a spider and add pasta to cabbage mixture in skillet. If there is not much liquid in the pan, add a few more ladlefuls of the cooking liquid. Raise heat to medium, and stir pasta and cabbage together so that the cabbage sauce coats the pasta. Cook for another minute or two until pasta is completely cooked and cabbage sauce has slightly thickened. Remove from heat. Taste and add more salt if necessary. Put a generous amount of pasta and cabbage on each plate or in pasta bowls. Add a generous spoonful of brown butter to each serving of pasta and gently mix with tongs. Add a shower of salted walnuts, top with two crispy sage leaves, and shred Parmesan cheese over top of pasta. Spoon a little more brown butter over all.

Serve!
