I have baked my chicken drumsticks for roughly 40 mins at approximately 420 F. I do not have a meat thermometer, so am looking for another way to determine its doneness. I did some research on this, and found that the juice should run clear; however, when I cut open my chicken, the juice that comes out is red. Does it sound like my chicken is correctly cooked to a safe internal temperature?

  • This link seems to give an answer. The gist is that juice color isn't a good indicator. (also is it "juice" or blood?) You need to test with a meat thermometer to be absolutely safe. amazingribs.com/tips_and_technique/… – MaxW Feb 16 '17 at 1:07

    OP, I'd really like to clarify something here. Look at the two top answers to this question: cooking.stackexchange.com/questions/29456/…. Do you mean that your chicken had juices that were lightly tinged pink, or that blood red fluid was visible? On the question I linked to, @rumtcho's answer was IMO probably the correct answer. I have the same feeling here and can't help but wonder if you have accepted a totally incorrect answer to the question you really intend to ask. – Jolenealaska Feb 16 '17 at 3:17

There is a common misperception about redness in chicken and what it means when gauging the doneness of the chicken.

Fully cooked chicken can leak juices that are tinged with red, and fully cooked chicken can have pink meat and/or redness in the joints or bones!

From the USDA:

The pink color in safely cooked chicken may be due to the hemoglobin in tissues which can form a heat-stable color. Smoking or grilling may also cause this reaction, which occurs more in young birds.

The acidity in the tissues can case a similar effect in the myoglobin.

From an unnamed research assistant at a major chicken processor speaking to Meathead Goldwyn at AmazingRibs.com:

"When the muscle is high in pH [low in acid] it takes a much higher temperature to denature the myoglobin. The meat may need to be 170 to 180°F before the myoglobin in breasts is denatured sufficiently to see clear juices. The drumstick and thigh have higher levels of myoglobin and they require an even higher internal temperature to denature it.

Red or purple bones and adjacent meat are caused by modern chicken manufacturing that can produce chickens big enough to slaughter at an age much younger than used to be the norm:

Darkening around bones occurs primarily in young broiler-fryers. Since their bones have not calcified completely, pigment from the bone marrow can seep through the porous bones. Freezing can also contribute to this seepage. When the chicken is cooked, the pigment turns dark. It's perfectly safe to eat chicken meat that turns dark during cooking.

-USDA

Furthermore, chicken that has not reached a safe temperature can have meat that looks done and juices that run clear!

If the muscle pH is low then the myoglobin is denatured at a lower cooked temperature. This means that one might potentially see clear juices at 150 to 160°F and this is not safe.

-AmazingRibs.com

According to the same source, the PH of the muscle tissue can be affected by the chicken's genetics or pre-slaughter stress. That and the fact the source doesn't want to be named causes unpleasant images to appear in my mind. But I digress...

In my experience, dark meat is best cooked to the point that it has begun to shrink away from the bone; which is way past the point of it having reached a safe temperature. Therefore laxity is better test of doneness than color for dark meat. Another way to describe that is that the joints between the thigh and the body and the thigh and the drumstick move freely.

To be considered safe, chicken must be cooked to or above 165 °F (73.9 °C). Chicken breasts are (IMHO) best right at that temperature. Getting good at hitting that temperature takes some practice. White meat is much more sensitive than dark meat to overcooking, so testing frequently with an accurate thermometer is really the only way to go until you have the considerable experience necessary to accurately gauge the meat's doneness without the thermometer.

Drumsticks are very unlikely to be undercooked after having been baked at 425°F (218°C) for 40 minutes. Watch for meat that has begun to shrink from the bone. You should be at or beyond that point already, which as I have shown, is a far better indicator of doneness than color. Of course, an accurate thermometer is always your safest bet.

Assuming you do not have a meat thermometer, I would recommend to cook the drumsticks until you see the tendons shrink and pull away from the ankle. When the skin has broken from the ankle, exposing a bit of bone on a good percentage of the drumsticks, they are done. My standard for drumsticks is 50 minutes in a 200˚C fan oven. This is only a little bit more time than your program, and roughly equivalent temperature.

I guess it should also be said: This advice does not apply if you are cooking from frozen.

if still red, cook them some more!

Chicken, especially drumsticks can handle being cooked a little bit too much.

Anecdotal, I cooked drumsticks last week, and left them about 1 hour (full pan of drumsticks); at about 40 minutes, I started pocking them to see how cooked they were, how easily the meat separated from the bones.
