Preheat your oven to Combi Steam, 400°F/200°C, 30% (low) steam. Lightly grease the base of a small ceramic or metal baking dish (just a little larger than your block of cheese, if possible), and set aside.
Pat your feta as dry as possible using paper towels, then leave it resting on a fresh paper towel to absorb any further moisture, and set aside.
7 ounces Greek feta
Mix the olive oil, honey and red pepper flakes in a small dish. Put the feta into your greased baking dish and drizzle half of this mixture all over the top of it.
1 Tbsp olive oil, 3 Tbsp honey, 1/2 tsp red pepper flakes
Put the dish into the center of the oven and cook for 10 minutes, by which time the edges of the cheese should be starting to turn a golden color. If you have a broil or grill setting on your oven, switch over to that now (keeping the same temperature). If not, increase the oven heat to 430°F/220°C.
Remove the baking dish from the oven and drizzle the top of your feta with the remaining honey/oil mixture. Return to the oven and continue cooking until the honey is caramelized and the feta is browning around the edges. This could take anywhere from a couple of minutes up to 8-10 minutes, depending on your oven setting. Watch it like a hawk if you're using a broiler/grill, as it'll go from golden to black in seconds.
Serve immediately, in the baking dish, sprinkled with the chopped walnuts and with fresh bread for scooping the cheese onto. This isn't a dish that will keep; you want to eat it hot as the cheese will firm up again as it cools.
1/4 cup walnuts, fresh crusty bread
