Remove the skin and kernels. 

Place the pickling lime in a large bowl with 8-10 cups of water and soak the apricots in it for 1-2 hours. 

Rinse and set aside on a towel to drain.

Boil the sugar with the water until you have a thick syrup. Let it cool. 

Place half an almond inside each apricot and drop it in the syrup.

Boil over strong heat until the sweet thickens. 

Finally, add the vanilla and the lemon juice and let it boil for a couple of minutes more.
