Are you sick of my pistachio packed posts? I don’t blame you, but really, this is a follow up on my obsessive post on Bronte pistachio paste, so bear with me and you will learn the easiest way to make ice cream, ever.
Now that I had finally experienced what a jar of pistachio paste from Bronte tastes like (bloody amazing), I seriously needed to do something about the low supply situation. A visit to my Greenacre-based Lebanese green grocer Abu Salim provided a good kilo of roasted unsalted pistachios for $15.00. I wouldn’t call us a perfectionist race, but when it comes to roasting nuts, the Lebanese are masters – they get it so right. The nuts were wonderful; the roasting concentrated and amplified their flavour brilliantly.
After shelling for an evening, thumbs sore with pain from the odd stubborn pistachio that refused to open, I ended up with a good amount to try making my paste. I was aiming for a smooth paste, and I knew my food processor was not up to the task. A quick tweet and the incredibly generous Mr Franz Scheurer was quick to donate his time and his Thermomix (what would have cost me $2000 to buy).
I wanted to create a pistachio paste that I could use in desserts, one that could have a decent lifespan, so I decided not to follow the ingredients of my jar of Bronte pistachio paste and instead omitted the milk. The paste would last longer, and I could add milk when I needed.
To create a good paste, I blitzed the pistachios along with some glucose and created an emulsification with grape seed oil. You could use any neutral oil. I didn’t take measurements and went with feel and taste. I stopped when the pistachios tasted slightly sweet and the paste was smooth enough for me (a bit of coarse meal is fine). The consistency needs to be slightly runnier than peanut butter. I went home and mixed in some cream with a small sample to test out the flavour and the gates of heaven opened and I heard a sweet song, and a choir or angels called out to me. Seriously, it was that good.
It is worth mentioning that if you want to make pistachio paste for ice cream, you may as well add some water into the blender to make the paste smoother. That way, you wouldn’t need a Thermomix, because with that much liquid, your food processor should do the trick. If you do add water, make sure you omit it from the recipe below.
The Ice Cream
I was aiming for a custard based ice cream, but as luck would have it, Jules from The Stone Soup posted a churn-free, machine-free lemon ice cream recipe. It looked incredibly simple, and I decided to give it a go. The basic idea is that by increasing the amount of sugar, ice crystals do not form. Jules folds lemon juice and icing sugar into whipped cream and simply freezes the lot for 6 hours. I did the same, but substituted pistachio paste for the lemon juice, and added some water to dissolve the sugar. The result was a beautiful. pistachio green ice cream with the texture of semifreddo, light, airy and delicious. I urge you wholeheartedly to try making ice cream this way. It is so simple – 5 minutes and you’re done, and it tastes ridiculously good.
The Recipe (adapted from The Stone Soup’s Lemon Ice Cream)
300 ml whipping cream
200 grams icing sugar
4 heaped tablespoons (or to taste) of pistachio paste, prepared as mentioned above
Whip the cream until soft peaks form
Mix icing sugar and pistachio paste and 1/3 cup of water until smooth (omit water if already used in paste preparation)
Fold the pistachio and sugar into the cream until evenly distributed
Whip the cream again until it gets to soft peak stage once more
Freeze for 6 hours or overnight
