Cover the inside of a cake tray with cling film

Chop the couverture into small pieces and place it in a bowl.

Put the orange juice in a saucepan and as soon as it boils, turn it off

Pour the juice into the bowl with the couverture and let it rest for 5 minutes and then stir until smooth

Add the tahini, the lemon and orange zest and mix well

Also add the orange liqueur

I break the halva into chunks in the bowl with the chocolate mixture

Mix well and place in the mold

Refrigerate for at least 5 hours
