first function, to give to a dog for tea and second to give the flavor to ham and lental soup
main ingredients are rice , bread , flour and a nice vegetable sauce ie carrot and herb lental. however you can vary this and use some different vegetables.
1 gram looks almost just like a sugar cube. but people don't know how big sugar cubes are anymore because they are not common. compared to a pea or lentil, 1 gram is larger. I would say that 1 gram = 2-3 peas or 4-6 lentils. one teaspoon (a measure of volume) is 5 ml. 1 ml of water = 1 gram. so a 1/4 tsp = 1.25 ml volume, if filled with water, will be 1.25 g. so if you fill the 1/4 tsp with peas or lentils and imagine about 1/5 less or more, that would be about a gram worth of them.
