Insert a toothpick in each tomato stalks (after being washed and dried). The tomatoes must be perfectly dry (otherwise the caramel "squirt").
Heat the sugar and water to a broken caramel (140°C or 284°F).
Out of fire, dip the tomatoes in caramel and place them on parchment paper or a baking sheet.
Allow to harden the caramel (about 5 min).
