Pre-heat oven to 400 degrees F.
In a high-speed blender, combine pumpkin puree, and arrowroot starch.
Pour puree into a pot on medium heat. Add in coconut cream, garlic, fenugreek leaves, tamarind paste, coconut sugar, ghee, cayenne powder, salt, and pepper.
Stir mixture frequently and let it all come together on medium-high heat. The sauce should thicken quite a bit over time.
Once everything is combined, taste and adjust spices as needed (to taste). I added in more spice, for example.
Add in shredded cheese and stir frequently until completely melted and combined with the sauce. Set sauce aside (remove from heat).
Meanwhile, in a stockpot cook your macaroni. Drain when finished.
Add cooked macaroni to the sauce and stir gently to combine (be careful not to break pasta while stirring).
Pour mac n cheese into a casserole dish. Top with extra shredded cheese.
Place casserole dish in the oven for 5-10 minutes or until cheese is melty and bubbling.
Remove and garnish with cilantro or parsley, and crushed red pepper.
Serve immediately and enjoy!
