The first time I used an artificial sweetener in my coffee, I never knew it was an artificial. Talking about complete ignorance. I thought why the sachets were so little. One or two were surely not enough to sweeten a regular cup of coffee. I used two sachets and was surprised with the results. The coffee became too sweet.
Now I have four Stevia sachets. Another artificial sweetener extracted from stevia herb. I know a little about it cause I used to raise two stevia pots on our house windows. I bought and grew it in hope I can use it directly in some food preparations.
I dumped the plants away after finding out that it tasted bitter sweet. A literal mixture of sweet and bitter tastes with a typical medicinal taste. The sweet component could be separated from undesirable substances but requires use of non-edible chemicals.
I am assuming the four 1-gram sachets I have are sweet without or with only trace of bitterness. I also assumes that one sachet is enough to sweeten a cup.
