(Or: How to Build an American Childhood from Finnish Pantry Staples)
So as you might remember from last time, I tried to make lime jello from scratch. I used French lime syrup, Spanish gelatin, and good intentions. What I got was an accidentally sophisticated gelée that looked like it belonged at a dinner party — champagne-chartreuse, barely sweet, elegant against its will. I ate the whole bowl standing at the counter and it was delicious, but it was not jello. Not the jello I wanted. Not the jello of my American youth.
My son had an even simpler critique: it wasn’t blue.

Yes, we fully believe that blue is both a color and a flavor, and he wanted BLUE. Blue raspberry isn’t a fruit that exists in nature. It’s an American invention, a color that became a flavor somewhere between the Slurpee machine and the candy aisle, a predilection that infiltrated my child’s mind from all those summer visits back to California. Despite having never set foot in a 7-Eleven, my kid knew exactly what he wanted his dessert to look like.
Where the lime gelée was just idle experimentation, the blue raspberry was a mission. Engineered from the start to be as artificial, as American, and as unapologetically blue as possible, while using nothing but European pantry staples.

Here’s what I had: powdered gelatin (made in Spain, ordered from German Amazon). Mysoda drink syrup (made in Finland), meant for home soda machines, available in half a dozen flavors. Citric acid (packaged in Finland, highly likely manufactured by an EU source), equally popular here for preserving berries and general household cleaning alike. And, most importantly, a bottle of blue food coloring (E133 Brilliant Blue FCF, the real stuff). Actually manufactured here and totally legal in the EU now, by the way, despite what you may have heard.
The Mysoda Raspberry syrup was chosen because its natural color is light pink — pale enough that it doesn’t fight the blue food coloring the way a red or dark berry syrup would. (Those turn purple. Purple is not blue. This distinction matters enormously if you are eleven.)

My first attempt undershot on two points. First, it was a gentle crystalline slate blue, the sort that looks especially lovely in muted Finnish winter light. It looked like it belonged on a bookshelf as a decoration, next to a nice pink Himalayan salt lamp. This was completely unacceptable.
The second fault was that it was undersour. Jello needs that tang, that slight mouth-pucker that tells you it’s jello and not just sweet gel. The lime gelée didn’t need citric acid because the Teisseire syrup brought its own tartness. The Mysoda syrup isn’t tart at all, it’s just sweet. So the citric acid did the work that “natural and artificial flavors” do in commercial Jell-O. Without it, you just have raspberry-flavored bounce with no bite. With it, you have jello.
Version 1.0 used a heaping half teaspoon. My son informed me it wasn’t enough.
Version 1.1: bumped to one and a half teaspoons. He took a bite, paused, and nodded. Formula locked.
The color instruction, for the record, is “add blue food coloring until it looks radioactive.” It needs to be deeply, aggressively, unnecessarily blue. The kind of blue that does not occur in nature and will leave your tongue stained in its chromatic aftermath. Blue like ranch dip and Fourth of July BBQs and that one fake bald eagle screech. If they were blue, that is. If you’re questioning whether you’ve added enough blue, you haven’t.

Where the lime gelée was champagne-chartreuse — restrained, elegant, French — this was nuclear. This was the opposite philosophy in the same dish. No subtlety. No sophistication. Just pure, committed, synthetic BLUE.
The result is jello that tastes like jello, wobbles like jello, and is blue enough to satisfy a child who has inherited an American aesthetic for candy colors despite growing up 8,000 kilometers from the nearest 7-Eleven. He ate it without complaint and asked when there would be more. In our house, that’s a standing ovation.
There’s one more chapter in this saga. What happens when you combine the lime and the blue? The answer is (conceptually, not visually) green. A glorious sort of green that can only be described as vaguely unsettling, which is why it’s called the Green Goblin. That one’s still in development. Stay tuned.
Blue Raspberry Gelatin Dessert
The “My Kid Wanted BLUE” Edition — Part 2 of the Jello Trilogy (see Part 1: Citron Vert Gelée)
Ingredients
- 300ml Mysoda Raspberry syrup (I trust you will substitute at your own discretion with a similar lightly-colored berry beverage mix)
- 24g powdered gelatin
- 1.5 tsp citric acid
- Blue food coloring
- 100ml cold water (for blooming)
- 400ml water
Method
Sprinkle 24g of gelatin over 100ml of cold water. Leave it for five minutes until it goes spongy. This is called blooming, and it’s essential — dump gelatin straight into hot liquid and you get lumps that no amount of stirring will fix, and then you’ll have to start over while your son watches you with the particular disappointment of a child who was promised blue cubes.
In a saucepan over medium heat, combine the bloomed gelatin with 400ml of water. Stir until it’s dissolved and steaming — not boiling, just hot enough to melt the gelatin completely.
Remove from heat. Stir in 300ml of Mysoda Raspberry syrup, then the citric acid.
Now add blue food coloring, a few drops at a time, stirring and assessing after each addition. You want DEEP blue. Committed blue. The kind of blue that stains the spoon and makes you briefly question your life choices. If it looks like it could power a small reactor, you’re there.
Pour into a dish. Refrigerate overnight, or at least six hours. When it’s properly set, it cuts into cubes cleanly and wobbles ominously.
Notes
- Mysoda Raspberry was specifically chosen because its light pink base doesn’t muddy the blue dye. Other berry syrups will give you purple. Purple is a different emotional experience.
- The citric acid is doing the heavy lifting here. The lime gelée (Part 1) didn’t need it because the Teisseire syrup was naturally tart. The Mysoda syrup is not tart at all. Without citric acid, you just have sweet raspberry gel. With it, you have jello.
- Overnight is ideal for setting. Patience is rewarded. Attempting to cut it at the four-hour mark will leave you sticky and sad.
- Adapted from the “Finland doesn’t sell Jell-O so I guess I’ll keep building it myself” school of expat cooking.

You can buy what I call jelly from a ‘British shop’ in Sweden that will send to Finland – raspberry and strawberry flavours at least. https://www.thebritishshop.se/products/hartleys-strawberry-jelly-135g?_pos=4&_sid=badf94cc0&_ss=r
Might save some work!
OMG you beautiful creature. Thank you so much, I am SO putting in an order with them this summer when I stock up on treats. Ever since Behnford’s in Helsinki closed, nothing has really filled that gap here. Probably because the costs are so high that most people only make occasional buys as treats, but yeah, it’s good to have an option for when the cravings hit.
