When I was much younger I was not a vegetarian and would often spread crab Patê into my sandwiches.
Crab Patê is a soft paste with the consistency of tooth paste. It has a salty taste and has a slight Mushroom and meaty flavour. To me it was the best thing to put in bread. I'm sure the main active ingredient is crab.
Now I am a vegetarian and I put salad cream and salad in my bread. When you think about it, most the volume of bread is CO2 gas. The gas is emitted by yeast before it is baked in the oven.
