To make ginger garlic paste, blend together a little bit of oil and equal parts ginger and garlic.
Make the Marinade
In a medium bowl, Mix together red chili powder, garam masala, cumin powder, coriander powder, turmeric, salt, oil, ginger garlic paste, yogurt, and fenugreek leaves.
Slice the SPAM into whichever shape you want. I did the classic slice.
Put the SPAM in the mixture and let it marinate. Since the meat is just SPAM, marinate for at least one hour. If using a raw meat, marinate for at least 8 hours.
Make the Gravy
Create cashew paste by blending together 1/3 cup whole cashews and 1/3 water.
In a pan, heat some oil. Toss in bay leaves, cinnamon stick, cardamom pods, and cloves. Stir constantly so the herbs brown but do not burn
Add chopped onions and a pinch of salt. Fry until the onions brown slightly. Then add the ginger garlic paste, cumin powder,coriander powder, red chili powder, garam masala, turmeric and fenugreek leaves. Continue frying while constantly stirring. You will end up with a dry onion mixture
Add the tomato puree and cashew paste and stir until one color. Let the sauce simmer for at least 15 minutes while you bake the SPAM.
Bake the SPAM
Preheat your oven or toaster over to 435° F. While the gravy is simmering, lay your marinated SPAM slices on a foil-lined tray.
Bake for 12 minutes, flipping halfway
When done baking, drop the SPAM slices into the curry and mix.
