All ingredients ready? Let's begin!
In a food processor, pulse the cashews into a fine powder.
Add the vinegar, lime juice, tahini, yeast, salt, garlic powder, onion powder, and turmeric to the cashew powder and pulse again into a smooth paste, scraping down the sides of the processor a couple of times.
In a small saucepan over medium-high heat, combine the water and agar-agar flakes. Bring this to a boil.
Turn the heat down to a rolling simmer and cook for about 5 minutes while whisking often until the mixture thickens and the flakes have dissolved. Set aside.
Generously oil a small shallow baking dish or a Pyrex storage dish, about 4” square or round.
Add the agar-agar mixture to the cashew base and pulse again to combine well, again scraping down the sides of the processor bowl. The end result should be smooth and creamy.
Using a silicon spatula, pour the “cheese” mixture into the baking dish and smooth the surface.
Cover with plastic wrap and refrigerate until the cheese firms up and is cold.
Remove the cheese from the baking dish to a cutting board, bottom (smooth) side facing up.
It should slide out in one piece by turning the dish over and tapping the bottom.
Slice and serve on a mezze platter or use it in a sandwich. This cheese should keep in the refrigerator for a few days.
Enjoy your homemade vegan cheese!
