Lamb Skewers

Whisk eggs in a bowl. Mix with 2 tablespoons of lemon juice, tomato paste and flour to make a marinade.

Peel shallots, finely chop and mix with the marinade and season with salt and pepper.

Trim lamb to remove skin and tendons as necessary and cut meat into 2 1/2 cm x 2 1/2 cm (approximately 1 inch x 1 inch) cubes.

Mix lamb cubes with marinade and let soak for 3-4 hours.

Rinse lemon and pat dry.

Pluck lemon balm leaves from the stems and cut into fine strips. Mix sour cream in a bowl with remaining lemon juice and season with salt, pepper and cayenne pepper. Stir in lemon.

Preheat a gas barbecue or oven broiler. Cover grill with aluminum foil.

Place skewers on the foil and cook for 5-10 minutes. Turn skewers and cook, watching carefully for another 5-10 minutes.
