Or what about a food game?? My ex told me she used to play this with her family growing up. They would blind fold one person each turn and the others would find something in the house that they wanted them to eat. Some stuff was gross stuff, some yummy, some non-edible like paper. Then they had to guess what it was. One time, she decided to make her mom eat ground coffee beans, which was never forgotten.
So try this. Once a week, some one gets to be a judge. The other 3 family members get to sit blind folded. And place two or three different mini cups (like the ones for ketchup) in front of each person. Take a picture of the cup, then the judge writes down what each person thinks about it before tasting. Like the tempature, the smell, if there's a noise if you shake it. Then the judge gets to write down what each person thinks of it, and what their guess is before they take off the blind fold. If it you want to, the judge can take a picture of every one trying it for a funny reaction.
And the judge can prepare the food any way they want to. Mash it, puree it, heat it, freeze it. And determine how much each person has to try of it. Like put a dab of vanilla extract in the cup, so the judge says "you only have to taste it with your tongue". If the judge puts in like two or three skittles, the judge can say "down the whole cup". If it's ice cream, the judge can say "lick the whole cup clean".
Do it once a week, with one family member being the judge each week. Make it fun with sweet stuff or sour stuff, toss in veggies or different kinds of meats. Write down what it is, and how it was prepared. By the end of a year, each person would have tried almost 80 new and interesting things.
