In celebration of National Mustard Day, French's teamed with Coolhaus Ice Cream for a promotion that combined mustard and ice cream.

The two companies collaborated to create French's Mustard Ice Cream. This offering was made available for a limited time at Coolhaus locations in New York and Los Angeles beginning on August 1. The co-branded flavor was served with an accompanying pretzel.

Coolhaus locations in Culver City had the flavor available from August 2 through 4 as well as through August 9 through 11. New York Coolhaus customers could purchase the branded flavor from a French's Mustard Ice Cream truck that traveled the streets. Coolhaus offered the French's flavor in the Hamptons on August 3.

The partnership with Coolhaus was an extension of French's "Not From France" campaign which focused on putting unexpected twists on the classic American flavor.
