For several reasons, I do not care how much fat, calories and cholesterol exist in my food. Instead, I focus on consuming foods that are nutrient-dense.
One food that I've started eating much more of recently is chicken heart, a very good source of protein, the B vitamins (especially B12), riboflavin, zinc, selenium and iron. Chicken hearts also provide folate, magnesium, manganese, phosphorus, potassium, sodium and copper.
But, as I repeat ad nauseam, the source of the food we eat helps determine its nutritional profile (and flavor). There is a huge difference between a chicken heart from a chicken raised on a factory farm, administered antibiotics and fed genetically-engineered and pesticide-laden corn and soy and a chicken heart from a chicken free to roam on pasture where it eats its natural diet (insects, worms, grubs, etc.). These two chickens are not the same animal.
(The same principle, I believe, holds for strawberries, butter, chocolate chip cookies, carrots, etc.)
I buy my chicken hearts at a local farmers' market from Grazin' Angus Acres, an elite farm that produces superior (nutrition and flavor) grass-fed beef, pastured chicken, pastured pork, milk and eggs.
Chicken hearts have a mild chicken flavor and do not taste or smell anything like liver, which many people find off-putting. My grandmother (born 1901 in the Old Country) fed chicken hearts to a family of six for $0.25, my mother claims. Needless to say, high-quality chicken hearts are now a little more expensive.
To cook the chicken hearts, I simply sauté them in—depending on my mood—butter, olive oil, coconut oil or rendered chicken fat (photo, above). Two or three minutes per side is all they need since they are small. I'll then season with a little unrefined sea salt, fresh ground pepper and sometimes a squirt of fresh lemon juice.
Since Grazin' Angus Acres only raises chickens from June through October, I've started buying extra, which I am freezing (photo, left) for use during the winter. No Perdue or Tyson chicken hearts for me!
