Tomato Choka is usually made with ripe, red, firm, juicy tomatoes, however, green tomatoes make excellent choka too. Apart from the obvious difference in colour, the flavour profile is different 
too.
The tartness of the green tomatoes are mellowed from roasting and tempered with the addition of sugar. A light sprinkling of ground jeera (cumin) rounds out the flavour profile of this choka. Eat the choka with bread, roti, or dhal and rice. Bread works too. Eating the choka with tortilla chips makes for unstoppable snacking. This choka can also work as a relish, and be topped over seafood or grilled vegetables.
