Mexican cuisine is known for its vibrant flavours and colours, and one of its most iconic dishes is Pollo Asado, or Mexican-style roast chicken. This dish is famous for its bright yellow skin, achieved through a combination of genetics and diet. The chicken is typically marinated in an array of spices and citrus juices, grilled, and often served with salsas, tortillas, rice, and beans. The name Pollo Asado translates to roasted or barbecued chicken, and it is a beloved dish in Mexico and beyond, with variations in Puerto Rico, Cuba, and the Caribbean. The secret to its mouth-watering taste lies in the marinade, which seals in flavour and moisture, creating a juicy and tender chicken dish that has gained worldwide popularity.

The colour comes from carotenoids, organic pigments, being absorbed by the skin
The colour of chicken skin is influenced by both genetics and diet. The yellow colour of Mexican chicken skin comes from carotenoids, organic pigments that are absorbed by the skin. Carotenoids are important dietary nutrients with health-promoting effects. They are found in maize, which is often used as a feed for poultry.
Carotenoids are also responsible for the yellow-orange colour of egg yolks. The pigmentation of egg yolks is influenced by the carotenoid content in the feed, with higher carotenoid levels resulting in darker yolks. The same carotenoids that cause the yellow colour in chicken skin are also found in marigold, which is used as a feed additive to enhance the colour of egg yolks.
In addition to diet, genetics also plays a role in the colour of chicken skin. A genetic mutation, likely a result of breeding, has led to a type of chicken that deposits more yellow carotenoid in the skin. This mutation does not originate from the red junglefowl, the presumed sole wild ancestor of the domestic chicken, but from the closely related grey junglefowl.
The combination of genetics and diet results in the distinct yellow colour of Mexican chicken skin. This colour is preferred by many consumers, who associate it with flavour and health. The preference for yellow chicken skin is not unique to Mexico, as consumers in other countries also show a preference for specific food colours.
While the exact reason for the preference for yellow chicken skin is unknown, it may be due to the perception that chickens with brighter skin are healthier or more fertile. The colour may also be simply aesthetically pleasing to consumers.

Marigold meals and concentrates are used to produce the deep yellow skin
The deep yellow skin of Mexican chickens has been a topic of interest for many. The yellowness is a result of carotenoids, organic pigments being absorbed by the skin. Carotenoids are naturally occurring pigments that give colour to many living things, including flamingos, birds of prey, and salmon.
The use of natural pigments is more effective than synthetic products in producing the deep yellow skin colour. In addition, a genetic mutation, likely from selective breeding, has resulted in a type of chicken that absorbs and deposits more yellow carotenoids in the skin. This mutation is believed to have originated from the grey junglefowl, a hybrid ancestor of the domestic chicken.
The preference for deep yellow chicken skin may be due to the perception of health and fertility associated with bright colours. The combination of genetics and diet contributes to the distinct appearance and flavourful taste of Mexican chickens.
The yellow colour of the chicken skin is not only aesthetically pleasing but also indicates the presence of carotenoids, which have potential health benefits. Carotenoids are antioxidants that can boost the immune system and promote overall health.
In conclusion, the deep yellow skin of Mexican chickens is achieved through the use of marigold meals and concentrates in their feed. This, combined with genetics, results in a visually appealing and flavourful chicken that is preferred by consumers. The yellow colour is not only a cultural preference but also indicates the presence of beneficial carotenoids.

A genetic mutation has produced a type of chicken that allows more deposition of yellow carotenoid in the skin
The bright yellow skin of Mexican chickens is a result of carotenoids, organic pigments being absorbed by the skin. Carotenoids are colourful substances that are transported by lipoproteins through the bloodstream to the target tissues. The typical corn and soybean-based commercial poultry diet does not supply the necessary amount and type of xanthophylls, a type of carotenoid, to produce the deep yellow skin that is preferred by many consumers.
Marigold meals and concentrates have been the most widely accepted for commercial use in poultry feeds. However, natural pigments are more effective than synthetic products in producing this colour. In addition, a genetic mutation, most likely a result of breeding, has produced a type of chicken that allows more deposition of yellow carotenoids in the skin.
The BCO2 gene, which encodes beta-carotene dioxygenase 2, plays a key role in determining the yellow skin of chickens. Mutations in the region of the BCO2 gene can result in a phenotypic change. Low BCO2 expression allows the deposition of yellow carotenoids in the skin. Scanning the single-nucleotide polymorphisms (SNPs) in the BCO2 gene revealed a G/A mutation in exon 6 of the BCO2 gene in white and yellow skin chickens.
The exact mechanism by which BCO2 affects skin colour is still unclear, but it is believed to be involved in the degradation process of carotenoids in the skin. There may be other factors at play as well, as the abundance and nature of lipoproteins can limit the capacity to obtain carotenoids. Furthermore, many species can metabolize carotenoids into oxidized forms that are deposited into the skin.

El Pollo Loco is another popular yellow chicken dish
El Pollo Loco is a popular Mexican-style chicken dish. The chicken is marinated in a blend of spices, citrus, and garlic, and then cooked over an open fire or in an oven. The key to achieving the signature El Pollo Loco flavour is in the marinade, which typically includes orange juice, pineapple juice, lime juice, garlic cloves, peppercorns, ground ancho, paprika, ground onion, cumin, coriander, oregano, turmeric, salt, and oil. The chicken is often cooked with the skin on, which results in a charred appearance and a crispy texture. The bright yellow colour of the chicken is likely due to the use of turmeric in the marinade.
El Pollo Loco is known for its bold, smoky flavours and juicy, tender meat. The dish is commonly served with sides such as flour tortillas and black beans, and can be used as taco meat, in a burrito, or on top of nachos. The Spanish word "pollo" means "chicken", and the dish gets its name from the fire-grilling technique used to cook the chicken.
The popularity of El Pollo Loco has led to the creation of various copycat recipes that aim to replicate the unique flavours and characteristics of the dish. These recipes often involve marinating chicken thighs or breasts in a blend of citrus juices, spices, and garlic, and then cooking the chicken on a grill or in an oven. Some recipes also include additional ingredients such as pineapple, hot sauce, and Mexican dried oregano to enhance the flavour profile.
One of the key aspects of El Pollo Loco that sets it apart from other chicken dishes is the combination of citrus flavours and charred skin, along with the bright yellow colour. The citrus marinade not only adds flavour but also helps to tenderize the meat, resulting in a juicy and flavourful dish. The charred skin provides a unique taste and texture that is difficult to replicate with other cooking methods.
The yellow colour of the chicken is believed to be a result of the use of turmeric in the marinade, which not only adds colour but also provides potential health benefits. The exact shade of yellow can vary depending on the amount of turmeric used and the cooking method, with some recipes resulting in a golden colour rather than a bright yellow.
