Often used as a salad dressing, homemade Thousand Island works well as a dip too. Simply mix mayonnaise with ketchup, mustard, vinegar, olive oil, lemon juice, Worcestershire sauce, chilli sauce, paprika and seasoning. To make the dip more substantial, you could also add mashed boiled eggs, finely chopped onion, red pepper and gherkins, or give it an extra kick with a drizzle of chilli sauce. For a real treat, serve with cooked, chilled tiger prawns and lemon wedges.
