To a saucepan, add heavy cream, sugar, salt and lemon zest. Heat over medium-low heat until very hot to the touch, about 3 to 5 minutes. It shouldn't be boiling but should be steaming.
Remove from the heat and pour in the lemon juice; give it a gentle mix. Pour the lemon and cream mixture into the halved lemons. Carefully transfer them to a cutting board or baking sheet and place in them in the fridge to chill, at least 4 hours.
To brulee them, add a teaspoon of sugar to the top in an even layer. With a kitchen blow torch, caramelize the top. Serve immediately.
