Mayonnaise

You can make mayonnaise in the blender, as here, or in a bowl with a wire whisk. Either way, just remember to add the olive oil as slowly as humanly possible as you blend/whisk. Once the oil has been emulsified into a creamy dressing, you can add a little Dijon mustard, some cumin, roasted garlic, fresh herbs, chilli sauce, or whatever you like for more fun and flavour. Use on seafoods and salads.
