to make a tetra mousse i pour the tetra into a jug, then i swill out the tetra container with a small amount of water (every little helps, lol) and add that. then add a rounded scoop of MAM slowly, blending at the same time to ensure no lumps. i then pour it over my jelly and leave to set for around 10-15 minutes, then i gobble it up like theres no tomorrow. lol
