Wash strawberries, cut in half and put in a pot, together with the vinegar and sugar. Heat until cooking, reduce heat and let simmer for about 10 minutes. Add 200 g of heavy cream to the strawberries and blend well. Let cool until at room temperature.
Whip the rest of the heavy cream and fold under the strawberry mixture. Place the ice cream mixture in an ice cream maker and let freeze according to the instructions. Afterwards, put the ice cream in the freezer until thoroughly frozen. (If you don´t have an ice cream maker you can put the mixture directly in the freezer. Just make sure to thoroughly mix the mixture every half hour in order to avoid too many ice crystals).
