Seafood sauce or Praise Thousand island dressing

Cherry Tomatoes- halved
To halve a cherry tomato, leave top and bottom and cut horizontally.. this leaves seeds in pattern

Stir together. This is a standard seafood cocktail.

To make a homemade seafood sauce (Divide by 5!! as large amount
Please note- I haven't tried this as yet!)
5 whole eggs
1 tablespoon Dijon mustard(French mustard).. this helps it combine
50ml lemon juice
50ml white vinegar
While beating with electric beaters on high or a fast hand whisk if preferred gradually
pour in oil (not pure olive oil as sets in fridge, some sort of vege oil, blended or canola oil works).. about 3 to 4 litres of oil
