As explained in the previous post this should be taken seriously in the modern kitchen as it allows great scope for innovation. In our quest to get the most of aroma, we wanted to be able to capture the aroma which fills the room when heating ingredients. For this reason apparatus was developed as a system of aroma capturing, based on a crude distillation still. While we have breifly mentioned the aparatus in a previous post, now I’ll tell you exactly how to use it. BUT, pressure cookers and heat and vapours can be dangerous, and if you are careless, the whole contraption could blow up in your face, while I see this a pretty … Read more

Historically vinegar has been used principally as food preservative, medicine and flavouring agent as well as a cleaning product, mordant or for odor removal.
