How to make my ice blend more slushy-like? I'm trying to make a chocolate ice blend from chocolate syrup, sweetened condensed milk, plain milk, and shaved ice (no measurements, eyeball and taste). I have a shaved ice maker and don't want ice chunks (also not sure how the blender can handle cubes), thus shaved ice instead of ice cubes go in the blender.
I want my ice blend to come out with a slushy consistency, but it keeps turning to liquid and more like just chocolate milk. I'm hesitant to add more ice since I like the strong taste I've got from the current (estimated) ratios.
How can I make the consistency more slushy-like?
You are fighting against entropy here because the heat of your ingredients and the heat generated by the friction of the blender’s blade are spreading out into the ice, melting it and giving you a homogeneous liquid.
So you have two things you want to reduce here: the total heat and the heat transfer to the ice.
Reducing the heat transfer to the ice is hard with shaved ice because it has an incredibly large surface area: hotter liquid can get everywhere in between the little tiny shavings. This causes rapid equalization and I do not see how you could solve that other than adding ice cubes.
For the total heat problem, try getting everything as cold as possible. This means putting everything into the fridge/freezer (even the blender’s jar if necessary) beforehand and minimizing the time it spends on the counter. You should also try blending for only the bare minimum. If everything still melts too fast, you could try freezing the milk or condensed milk (in something which will not explode when the milk expands, providing extra ice.
