With your prawns
try natural yogurt with lemon juice, a squirt of tomato puree and black pepper.
Just like Marie Rose sauce. You can use that as a base to add garlic, herbs,tabasco sauce, smoked paprika - all sorts.
Natural yogurt with a bit of curry powder or paste or tikka apices also yummy.
Roasted red pepper and garlic whizzed up
to a smooth paste - I could go on, but better not!
Enjoy xx I'm glad your mum is helping you.She must be very proud of your achievement.
