First, I confess.
I'm not a fan of organic food.
I'm not a fan of locally grown food.
and I'm not rich and like to buy cheap grocery if possible.
But, I like varieties, and freshness.
Thus I like farmer's market.
I've only been to two farmer's market at Phoenix, one at roadrunner park, one at downtown Phoenix. Both are good, but I like downtown one better.
The best thing at farmer's market, is to buy some varieties that are different from what's in the supermarket. Actually, don't expect them to be in any supermarket.
My wife loves the apricot I bought, because it tastes so much like what she had years ago at her grandparents' country-side home. The apricots are small, with big pits. You know no supermarket will sell these ugly apricots. Furthermore, they are so ripe and delicate, I almost always crashed some of them on my way home, that we have to eat them immediately at breakfast. Yet it's not eat, they almost immediately melted in your mouth, and all you need to do is to spit out the pit, and put another one into your mouth, and you can do this again and again until all apricots are gone, or extreme mental strength, stop and tell yourself to leave some for that afternoon. Though pricey than supermarket, It is worth every penny.
(Well, OK, my son, who is 3 years old, proved that we were wrong on the above claim: didn't melt! popsicle please! )
Same thing for many other fruits, breads and vegetables.
For example, the long beans I bought here is very fresh, which make them a perfect choice for a summer veg salad, while the ones I bought from Chinese market is so old that I even swore I will never touch it. Farmer's market made me change my mind.
To have such a farmer's market, is a total bless to my life. I wish I had found it earlier.
