   Consider the family of Dirichlet $$L$$-functions of all even primitive characters of conductor at most $$Q$$, where $$Q$$ is a parameter tending to infinity. For $$X=Q^{\eta }$$ with $$1<\eta <2$$, we examine Dirichlet polynomials of length $$X$$ with coefficients those of the Dirichlet series of a product of an arbitrary (finite) number of shifted $$L$$-functions from the family. Assuming the Generalized Lindelöf Hypothesis for Dirichlet $$L$$-functions, we prove an asymptotic formula for averages of these Dirichlet polynomials. Our result agrees with the prediction of the recipe of Conrey, Farmer, Keating, Rubinstein, and Snaith for these averages. One may view our result as evidence for the “one-swap” terms in the recipe prediction for the general $2k$th moment of the family of Dirichlet $$L$$-functions.
