Hi LouP, you could use lemon juice instead of lime. The Shakkar is an unrefined sugar so I think a light brown sugar would do. As for the pineapple juice, I used stuff that was made from concentrate (longlife), not freshly squeezed. It would probably still be quite nice even without the pineapple juice, but I think the others are a bit more important. I only use lime because it just seems slightly more perfumed in smell and flavour. Thanks for trying the recipe and I hope you enjoy it. Please let me know how you get on.
