Talking about design.. I randomly ran into an industrial design website presenting quite interesting products w/ pending patents. Here’s one of them.
Here is Stem – as they call it – designed to allow the cook to spray the juice directly from a citrus fruit. No need to cut and squeeze your fruit to get the juice out. It sprays and distributes the juice evenly.
Would be great to use on finger food like baby carrots, cucumbers etc. Or you could even put it on the table just like salt and pepper – so anything lacking lemon zest, you could simply spray some. Aaand without the risk of overdoing it!
