A few days ago, I started sprouting a batch of lentils. This morning, I took some of the beans, now with 0.5-1 mm shoots growing out of them, tossed them in salt, pepper, and paprika, and spread them in a single layer on a pie tim, which I baked in a preheated 250F oven for about 20 minutes. When they came out they had a lovely flavor, but were a bit gummier than I'd like. I'm going to perform the experiment again with the remainder of my sprouts tomorrow, but I'll probably change something. What I'd like is something crunchier--I've had toasted chickpea sprouts that are crunchy and delicious, and I can only hope that a similar effect can be achieved with lentils. Does anyone have any suggestions? I could bake them longer, change the temperature, only add the salt after cooking (as one does to prevent beans in soup from toughening up)... Also, by tomorrow the sprouts will be more developed, with longer shoots. I suspect the chemical changes that take place will also make a difference.
If they're gummy, they might still have too much moisture in them. Try roasting them at higher temperatures or longer and see if they crisp up.
