In a mixer combine the whole milk and sugar. Whisk on medium speed until sugar dissolves.
Add lemon juice and salt and whisk again for about 1 to 2 minutes on medium speed.
Add heavy cream and lemon extract. Whisk until fluffy, about 3 to 5 minutes.
Cover your bowl and place in the fridge for at least one hour. I let mine age overnight.
Remove and transfer liquid to your ice cream maker bowl. Make sure it's frozen prior!
Place your bowl on the ice cream machine, set it all up and turn on. Let it whir for about 10 to 15 minutes.
Now line a shallow dish or container with parchment paper. Pour the ice cream into that dish. Pop in the freezer for at least 4 hours, or overnight. If leaving for an extended period make sure you cover it.
Remove dish from freezer. Use the parchment to lift out the ice cream and set it on a board.
Use cookie cutters or scoop out by hand.
Place ice cream on one cookie, then place the second cookie on the other side. Give it a little squeeze.
Voila, ice cream sandwiches.
You eat them straight away or save them for later.
If saving for later remember to wrap them tightly in plastic wrap.
Serve with a big old puckery smile!
