Bistro Half Chicken with Baby Bellas, Spinach & Lemon Pan Sauce

Score: 8/10

A conceptually strong and highly appealing bistro-style recipe with excellent instructions and safety notes. The only significant flaw is the ratio of thickeners to liquid in the pan sauce; the butter and flour quantities need to be increased to deliver the promised glossy texture.

Strengths

Excellent safety reminder to keep an oven mitt or towel on the hot skillet handle.
Smart use of a weight (brick or heavy pan) to ensure an even, crispy sear on the chicken skin.
Great one-pan methodology, utilizing the rendered chicken fat and fond to build the sauce.

Issues

medium / ingredient_usage: 1 teaspoon of flour and 1 teaspoon of butter are insufficient to properly thicken and enrich 3/4 cup of chicken broth. To achieve a 'glossy' pan sauce, more fat is needed to mount the sauce.
low / clarity: Butter and flour are listed as 'optional', but without them (or without a significantly longer reduction time), 3/4 cup of broth simmered for only 2-3 minutes will result in a thin, watery liquid rather than a sauce.

Suggested fixes

Increase the butter to 1-2 tablespoons to properly emulsify (monter au beurre) and finish the sauce.
If keeping the flour as a thickener, increase it to 1 tablespoon to balance the 3/4 cup of broth, or omit it entirely and rely on a longer reduction and cold butter to thicken.
Remove the 'optional' tag from the butter, as it is critical for achieving the 'glossy' texture promised in the description.
