I usually make rujak with gula jawa/coconut sugar. Today, I´m craving something fresh, spicy and sour but too lazy to make Sambal rujak. So, I made this fruit rujak with lime juice inspired by Teh Niknik. Danke! Ingredients:
Juice of 3 limes
12 tablespoons sugar
300 ml water
1-2 Red chillies/bird´s eye chillies, deseeded
salt
Fruits: a half of pineaple, 1 apple, 1 pear, 1 mango --> cut fruit into long thin pieces

directions: combine water and sugar in medium saucepan. Stir over heat, until sugar dissolves. Let them cool. Pour in lime juice in syrup. Add chillies and fruits.
