Heat balsamic vinegar and sugar together in a saucepan over medium heat and stir until the sugar dissolves into the liquid, then bring to a gentle boil.
Cook the vinegar and sugar together at a gentle boil until it reaches a thick, sticky consistency (or whatever your preference) but be careful it does not burn.
Allow the balsamic glaze (or balsamic syrup) to cool completely before transferring to a serving jug.
Tomato salad
Slice tomatoes into pieces and arrange on a serving platter.
Place the whole burrata cheese in the middle and scatter torn basil leaves over the top.
Drizzle over the balsamic glaze and garnish with olive oil and salt and pepper.
