drupe

/dro͞op/

Noun BOTANY

  1. a fleshy fruit with thin skin and a central stone containing the seed, e.g., a plum, peach, cherry, almond, or olive.

Growing up, I had childhood fantasies of joining James and his band of insect comrades on their magical journey aboard their flying peach in Roald Dahl’s children’s story James and The Giant Peach.  I could just imagine sitting on top of the flying sunkissed, fuzzy peach skin watching the stars float by with my friend the grasshopper or tucked into the warm, cozy peach pit sleeping in between the ladybug and the earthworm. A grand adventure! 

Childhood fantasies aside, peaches are pretty cool.  Great taste, perfect ombre of coloring and are a key component of one of my favorite desserts, peach cobbler. And cooler still because they are drupes.  A drupe, also known as a stone fruit, is derived from the ovary wall of the flower. It is essentially a fruit that has a flavorful, fleshy outer layer with an inside hard shell or pit (endocarp) that holds a seed. Drupes are classified as one-seeded and indehiscent. Indehiscent fruit do not split to release their seeds. 

Many drupes attract animals due to their flavorful, fleshy outer layer. At times they may not eat the stone portion, but often they do. While being passed through the digestive tract, the hard endocarp of the pit is partially reduced by the acid in the animal’s digestive tract. This process does not harm the seed and actually aids in enhancing germination due to the thinner skin of the pit. This process is known as scarification. For some seeds, scarification is a necessary part of successful germination. 

Some drupes are referred to as freestone.  This means that the pit of the fruit peels away easily from the fruit. Clingstone is used to describe a drupe whose flesh requires work to pull the pit away from the flesh of the fruit.  Other examples of drupes would be apricots, olives, loquat, plums, cherries, mangoes, pecans, and amlas.

You can find fresh local peaches this week at our Wrightstown and Doylestown Markets!

Meet the Humble Carrot

Sure, the days feel shorter than ever, as the sun crests behind the hills in Eastern Pennsylvania at around 4:30 p.m. or so, but that doesn't mean that your cooking has to become equally dreary. Really, the dark, cold nights are an incredible excuse to bust out the stockpot and whip up a hearty Irish-style beef stew with maple and stout, or a pile of roasted root vegetables, seasoned well and caramelized on a sheet pan in the oven. Maybe even a carrot tart with ricotta and feta will feel just indulgent enough.
