Here's an excerpt that I found: The Rainier cherry is the sweetest, prettiest and most pampered of cherries, as delicate as it is lucrative. Washington state requires Rainiers to reach a minimum of 17 brix -- a gauge of sweetness -- before they can be picked. To compare, a peach that registers at 13 brix is considered perfectly sweet. Olmstead doesn't pick until the cherries reach at least 20 brix."
So naturally when the rainiers are in season, there's no reason why we shouldn't just pamper ourselves a little bit especially since we have the comfort of getting this imported fruit readily available in our local supermarkets! If you had ate rainier cherries before, you will know that they are slightly bigger than the dark red variety, with a skin that is so thin that any slight mishandling will bruise it, the yellowish flesh is way sweeter and juicier than the red bing cherries! In fact I tried a little experiment where I savoured some rainier together with some bing cherries and without fail, if I were to eat a rainier first before a bing, the bing cherry would taste sour but never the vice versa. So what are you waiting for? Head out to the nearest Cold Storage or Marketplace and grab yourself a box of these simply wonderful little jewels!
