Soak the almonds: Place the almonds in the blender, pour the hot water over them, and let them soak for about 15 minutes.
Blend the almond mixture: Add the lemon juice, 4 tablespoons olive oil, garlic, and salt. Blend with a powerful mini blender until the mixture is as smooth and creamy as possible.
Prepare the cheesecloth: Line a sieve with cheesecloth and place it over a bowl or pot.
Add the mixture: Spoon the almond mixture into the cheesecloth. Gather the sides of the cloth at the top and secure them with a rubber band or kitchen twine.
Let it rest: Place the sieve and bowl in the refrigerator for about 12 hours or overnight. During this time, the previously creamy almond mixture will become noticeably firmer.
Preheat the oven: Preheat the oven to 180°C / 350°F convection.
Prepare the almond feta: Spread about ½ tablespoon olive oil over the bottom of a baking dish. Remove the almond feta from the cheesecloth and carefully place it in the dish as a small loaf.
Bake: Bake the almond feta for about 40 minutes, until the surface is lightly browned and begins to crack.
Prepare the dill oil (optional): Briefly sauté the chopped dill with 2 tablespoons olive oil, finely chopped garlic, and chili flakes to taste, until the dill becomes slightly crispy. Spoon the dill oil over the baked almond feta before serving.
