Gluten Free Frozen Strawberry Vodka Martini

There's much debate over martini making these days. Some people defend to death what makes a good martini: vodka or gin. There's also debate about whether martinis have to have vermouth or not. Well, I'm not a fan of gin and we didn't have any vermouth in the flat the day I made these. Although, to be honest, the only time my martinis ever have vermouth in them is when I get them from a bar.

Please  vote for me!

For me, it's the vodka that makes it a martini, but call this what you want, a frozen martini or a vodka freeze. It doesn't matter, really; it's good. We had some fresh strawberries from Spain that were nearing the end of their life and not being able to stomach seeing them wasted, I blitzed this beauty up and served it with dinner. Also, I served them in red wine glasses, as you can see. You get more without having to fill up multiple times and if you're having the kind of day where you need one of these, the last thing you want is for your glass to be empty after five sips! ...
One more thing: if it bothers you, go ahead and add the vermouth back and make this into a proper martini. Swap the vodka for gin, too, if you're so inclined.

Ingredients: 

For the  frozen martini 
1 tbsp fat-free strawberry yogurt
1 1/2 tbsp caster sugar
2oz vodka, ice cold (I keep a bottle of vodka in the bottom of the freezer)
8 large strawberries, sliced
ice cubes

All right, let's blitz:
Tumble the berries, vodka and caster sugar into a tight-closing container. Shake vigorously. Leave to allow the fruit to macerate with the vodka and sugar.

Once macerated, tip the contents of the container into a blander along with some ice and yogurt. Pulse until desired consistency is reached.

Add more ice and pulse if you want it the consistency of a daiquiri or margarita. Add more yogurt for a smoothie-like texture.
Serve with a fresh strawberry and enjoy.
