(NBC) - The popular fast food chain, McDonald’s is promising more Szechuan Sauce after its first batch sold out.
McDonald’s offered the rare condiment from the 1990’s on Saturday after pleas from the creators of the popular show, 'Rick and Morty'.
However, the promotion ended with many fans empty-handed.
Some packets of the sauce even ended up on Ebay, selling for sky-high prices.
McDonald’s has since acknowledged its super-limited batch was not enough not meet the demand.
It says the sauce will return in the winter and will be more widely available than Saturday’s promotion.
