Is Moominmamma's family really getting tired of her cooking? It seems impossible, but Little My unabashedly claims that she is getting very bored with always having pancakes, and Moominpappa at least implies that the best dish he ever had was one not cooked by his beloved wife. As always, when in a quandary, Moominmamma consults Grandma's book of recipes and cures and, sure enough, finds "What To Do When Your Family Grows Tired of Your Cooking". Taking Snufkin along, she embarks on the journey that the recipe calls for, to find the secret ingredient necessary for the Irresistible Dish.
