In a milk pan, heat the olive oil and butter until completely melted.

Finely dice the onion and mince the cloves of garlic before adding to the melted butter/oil mix.

Cook for 5 minutes until the onions have softened.

While the onions are cooking, add the pasta to a pan of boiling water and cook according to the packet's isntructions (for roughly 10-15minutes).

While the pasta is cooking and once the onions are cooked, add the flour and dried spices to the butter/onion mix.

Stir well until a dry pasta forms and the butter has been completely incorporated into the flour.

Next, add the milk to the paste a little at a time, stirring well each time first to create a smooth paste, then a thick sauce before adding the rest of the milk.

Keep the pan on a low heat and stir constantly for 5 - 10 minutes until the sauce has begun to thicken and coat the spoon.

Grate the cheese into the sauce and stir well until melted.

Finally, add the sour cream, roasted red peppers (sliced), sweetcorn and chipotle paste.

Stir well until all ingredients are fully combined and the sauce is thick and bubbling.

Test the sauce and add seasoning at this stage if needed.

By this point the pasta should be cooked.

Transfer the pasta into an oven dish and pop over the cheese sauce.

Pop under the grill on a medium heat for 10 minutes or until the top has turned golden.

Serve with fresh coriander, pickled jalapenos and crispy onions in small bowls to top the mac and cheese.
