You eat the white petals of the feijoa flower, which have a sweet taste.
One day last summer I looked down at the plate I was eating from. It was white, scratched, cheap, probably from Ikea or Gifi, utterly depressing and unworthy of the fine meal I had prepared. So I threw them all out, it and everything like it went in the bin.
I've been replacing them with fine porcelain bought cheaply, mostly from secondhand sites on the Internet. The plate above is one of seven I bought for 16.45€ (total, commision and delivery included) from the Vinted site. It is Villeroy & Boch and a single dessert plate like this from their current range would cost about 25€ on their site. The maximum I will pay secondhand is 4€ per plate and it is very easy to find secondhand Limoges porcelain and similar at that price.
We do of course have a full set of matching china for special occasions, but you can't use that for everyday.
I bet it tasted great too.
