Garlic Shrimp Mac and Cheese

Preheat broiler/grill on high.
Mix together Breadcrumb Topping.
Heat oil and melt 1 tbsp butter in a large, deep skillet or heatproof pot on the stove over high heat.
Add shrimp, sprinkle with pepper, then cook for 1 minute. Add garlic and cook for another minute until the shrimp has changed colour but not fully cooked.
Transfer to bowl. Turn heat down to medium.
Melt remaining butter. Add flour and cook for 1 minute.
Pour milk in slowly, stirring as you go. Once incorporated and lump free (use whisk if needed), stir in Seasonings, then water.
Once the liquid is hot, add macaroni. Cook for 8 minutes, stirring regularly, until macaroni is almost cooked through, then take it off the stove.
Add cheeses and stir through, then add shrimp. Taste for salt - tweak if needed. It should be saucy (see video) - it gets absorbed. Should still be saucy at this stage - sauce gets absorbed/thickens more in next step.
Sprinkle over breadcrumbs, then place under the hot grill for just 2 - 3 minutes until the top is golden.
Sprinkle with parsley if desired and served immediately!
