The tinting was a new thing for us. We learned it on Youtube! And yes, the kids are frosting fans, too. My in-laws scrape all the frosting off. They think it's too sweet. The Dutch don't do birthday cakes like we do. For the most part, when you are invited for someone's birthday, it's not like "time: 3:00pm". It's an all day thing and people pop in throughout the day and stay for an hour or so. So you may have only one person there at one time and 20 at another time of day. As people come in, they are offered coffee (or tea) and a piece of some baked good like apple pie or something. Cake is generally for a children's party and then it's more like really thin layers of sponge with whipped cream on them. Butter cream is not a "thing" here. Just like brownies and cheesecake were not a thing here when I moved over here. I had to learn how to make all my favorites from scratch because they didn't exist here. I did find a brownie once back then, but it was not good. It was dry, dense, and didn't have much chocolate flavor. In the last 5 years, brownies have become more popular, but I have yet to find one in a bakery that's as good as even the box mix ones you can make in the states. Cheesecake is slowly emerging, but it's not as popular as brownies yet. And about 5 years ago, cupcakes became all the rage and everyone was suddenly trying to make cupcakes, but again, they are not as good as what we know. They use a more dense batter, more like pound cake. Not the light, fluffy cake we have. Anyway, it's a very different thing here.
My MIL used to get very disgruntled because we actually did set a time for our parties since my friends are all foreigners and we met at school learning Dutch. We all have different traditions and none of us like the Dutch party that goes all day and you spend your day running back and forth to the kitchen to serve guests as they arrive and you don't get to actually enjoy the party. So we all just set food out on a table and people can serve themselves, and we have one moment to sing and blow out the candles, and then cut the cake. We will serve everyone their first cup of coffee, but after that, it's serve yourself, and we don't do the cake WITH the coffee. So my MIL kept grumbling that she couldn't drink her coffee because she didn't have cake. When were we cutting the cake? Can I have cake now? She really doesn't like the American traditions. They don't do the whole sing happy birthday and then blow out the candles thing, so she doesn't get that that's a huge moment for the birthday person. She thinks it's rude to not give people cake with their coffee, to make them wait for everyone to get there and blow out the candles.
