Fresh Is Best. No matter how many mugs it takes you to wake up in the morning, your personal coffee turnover isn't going to be nearly equal to that of your local coffee shop, which means your beans are probably a bit longer in the tooth than the cafe's are on any given day.
Sesame seeds, despite their tiny size, are a valuable cash crop. They come from the Sesamum Indicum plant, which is native to Africa but is now found mostly throughout Asia, with Myanmar and India the largest producers.
Sesame seeds are used liberally in cooking. The seeds ground with olive or any other vegetable oils to prepare semi-solid, flavorful paste, which is then added to different cuisine. Dry, roasted sesame seeds and vegetable oil are ground into a thin light brown color paste known as tahini.
