Why was there not enough foam in my garlic foam with soy lecithin?

This was my first attempt at making a foam using soy lecithin. I used 3 garlic cloves, 2/3 cup water, 2/3 cup milk. Then i used an immersion blender. I got a bit of foam on top but there wasnt a lot of it. It felt like a waste of a lot of milk. How much foam should I be expecting?

For now, I put the foamy mixture in the fridge, is there a way to salvage and get more foam?

Just an idea... I've had problems making foam because of hard/basic tap water (a lot of chalk in the water) - making frape though, not garlic foam:) Foam will more easily form in soft water as you can easily test with a piece of soap. If you have hard tap water you could try using boiled water (some of the chalk in the water will react and leave a residue on the bottom of the pot) or bottled water with pH 7 (neutral). Another idea would be to add just enough acid for neutralisation but I imagine that could be a bit tricky and you'd risk the milk curdling so I wouldn't recommend it.

How much lecithin do you need to make foam?

By weight soya lecithin should be used in a concentration of 0.3-0.8% for foam and 0.5 to 1% for emulsions. As an emulsifier, it can be whisked into the chosen liquid; while for foams or mousses, a stick blender held just below the liquid's surface creates maximum yield.

Why do we add soy lecithin to foams?

In soy lecithin foams the stabilizer is always soy lecithin. It allows the foam to last longer without greatly changing the nature of it. Soy lecithin is typically added by weight as 0.3% to 1% of the total weight of the liquid.
