Get your frozen seafood mix ready. Place it in a colander under cold running water to defrost. This helps prevent it from releasing too much water when you cook it. Once defrosted, drain it well and pat dry with paper towels.
Peel and finely chop your garlic cloves. You want them nice and small so they infuse the oil beautifully.
Wash your cherry tomatoes and halve them. If you're using larger fresh tomatoes, you can score the bottom with a small 'X', blanch them in boiling water for 30 seconds, then peel and roughly chop them.
Pick the leaves off your fresh basil and set them aside for garnishing later.
