Okay, lets assume the protein portion is handled. We could pour some Low-Carb Grow! into whatever other bar material we come up with.
Given this, we are left with coming up with a suitable bar. It has to have product characteristics such as:
- size
- texture
- cost
- shelf life
- nutrients
- dryness
- cohesion
If the bar is too small, its not going to provide enough nutrients or satiety to make it desirable. Basically, the bigger the better if nutrients are not sacrificed.
By texture, I mean chewability and density. I’m not into chewing on rocks or cardboard and I wouldn’t want it to dissolve like cotton candy. Somewhere between leathery and crunchy might be okay though.
Nutrients are fairly obvious, but we also have to avoid psuedo-proteins and unfavorable proteins like soy. We just might want to avoid turning the bar into a complete fibre bomb too.
For dryness, if it’s wetter than chalk and not a liquid, then it would probably be workable. For example, some type of nougat or taffy consistency would work, especially if coated.
Finally, I’d like it if the thing would stay as one bar. We’ve already got powder and liquid options, we don’t need that type of behavior in our hypothetical new bar!
Maybe there is a way to get away from the dry bar concept and go towards something like a concentrated gelatin filler like sugar free Jello. This obviously comes premade in a plethora of flavors and would go well with dried fruits.
Protein could be mixed into the gelatin and then we are left needing some type of flash cooked coating or maybe a wafer. For the carb inclusive bar we could possibly roll or mix the gelatin with rolled oats and flash cook it.
For the low carb version, maybe we can up good oil content to help get a feeling of fullness without the oats or other bulk. Maybe dust the filling in some type of oily nutty flour or something prior to cooking.
Anyhow, I think the water and gelatin based filler has some advantages in terms of size, weight, cohesion and cost if it can be made chewy and coated. Just trying to think outside the bar…
