Take a tin of sealed condensed milk. Place it in a pressure cooker (or use a pan). Cover it with water. Close the lid.
Cook for 1 whistle on high flame. Then cook on low flame for 30 minutes. If you use a pan, cook 2.5 hours on low flame. If there is little water until the process finish, add it.
Remove from heat. Leave it for a few hours or overnight.
Let the all pressure goes out. And you will get great caramel.
Add 250ml of heavy cream or fresh cream into a bowl. Beat until it reaches to stiff peaks. Make sure your cream is chilled.
Add all the caramel that we get before.
Mix until everything is well combined.
Transfer it to an airtight container. Tap it twice.
Cover with cling wrap or plastic sheet. Make sure it touches the cream.
Freeze it for 4-6 hours. After, scoop it and serve.
Add caramel sauce if you want and enjoy your homemade English toffee ice cream.
