With the Chefsteps recipe they use a whole chicken. I was just looking through Modernist Cuisine and an example blonde chicken stock for them uses chicken wings instead. What'd work best?
Also, they put the wings in water, bring to a boil, then strain and after that they ditch the water and put the wings and the rest of the ingredients in the pressure cooker. Why blanch the wings/have them in water and bring to the boil first? If using the Chefsteps method would it be improved if the bird was jointed and then treated the same way as the wings (put the chicken in water, bring to a boil, then discard that water)?
