Suppai Lemon Jelly DIY candy kit — English instructions, step by step with video

Suppai Lemon Jelly: English Instructions, Step by Step

Suppai Lemon Jelly — suppai means “sour” — is a candy kit you play rather than just eat. You make six lemon jellies that look identical, but some are made with the sour base and some with the sweet one, and once they are sitting in the tray nobody can tell them apart. Then you hand them round.

The short version: Water only, no microwave. Make the lemon jelly, keep the sour batch and the sweet batch separate, and spoon both into the six small moulds. Do it while nobody is watching — the game only works if the players don't know which is which.

What You're Making

Sour

The suppai base

A green sachet printed すっぱいもと — “sour base”. The sour ones are seriously sour.

Sweet

The amai base

A pink sachet printed あまいもと — “sweet base”. These are the safe ones.

Moulds

Six jellies

Six small round moulds, filled from the larger wells. Finished, they all look the same pale lemon yellow.

How many?

You decide

How many sour and how many sweet is up to you. That is what makes it a game.

Lemon flavour, no fruit juice. Water only, no microwave and no stove — it belongs with the other kits that need no microwave.

It Is a Party Game That Happens to Be Edible

Think of it as Japanese candy roulette. The making is quick; the fun is the moment someone bites into a sour one. It works best with three or more people, and it is one of the few kits that is better shared than made alone.

If you are planning a group activity, our kit-by-kit party plan covers which kits suit a table of kids and which need one adult per child. This one is firmly in the easy group.

How to Make It

The whole kit, start to finish, filmed by our team. By the end the six jellies look exactly alike — which is the whole game.

One thing to know We don't reprint the exact water quantities here, and you shouldn't trust any site that does. Every kit prints its own measurements on the tray or the back of the pack, they differ between kits, and makers change them between production runs. Use the diagram on your pack for the numbers. What this guide gives you is everything the diagram doesn't: what the pictures mean, what order to work in, and where it goes wrong.
  1. Shake the sachets before you open them

    Both bases are printed あけるまえに、粉を下におとそう — “before opening, tap the powder down”. Tap them so nothing is lost when you cut the top.

  2. Make the lemon jelly in the large wells

    Follow the numbered pictures on the tray for the water. Stir until it is smooth and evenly yellow.

  3. Keep the sour and the sweet apart

    The sour base and the sweet base each go into their own batch. Do not let them mix — once they are combined there is no game.

  4. Spoon them into the six small moulds

    Fill each mould from one batch or the other, and remember (or don’t) which is which.

  5. Let them set, then hand them round

    They set quickly. Offer the tray and let everyone pick one.

If It Did Not Set

Three causes, in the order they actually happen:

What to check

  • The powder was not fully dissolved. Lumps stop the jelly firming up. Stir until there is no grit left before you spoon it into the moulds.
  • Too much water. A runny batch will not hold its shape in the small moulds. Measure against the line on the tray.
  • You moved it too soon. Give it a moment to firm up before you lift them out.

Water is behind more failures across this whole range than anything else — we wrote up why the water is almost always the problem and what to pour if your tap water is hard.

What the Japanese on the Sachets Says

The pack is entirely in Japanese, and a handful of words do most of the work.

The words worth recognising

  • すっぱいもと (suppai moto) — sour base. The green sachet.
  • あまいもと (amai moto) — sweet base. The pink sachet.
  • あけるまえに、粉を下におとそう (akeru mae ni, kona o shita ni otosou) — “before opening, tap the powder down”. Printed on both. It is the first instruction, not decoration.

Common Questions

How sour is the sour one?

Properly sour — that is the point of the game. Keep a sweet one in reserve for anyone who doesn’t like it.

Is it actually edible?

Yes — it is confectionery sold as food. Meiji declares none of the designated Japanese allergens for it; it is made in a facility that also handles walnut, wheat, egg and milk. Always check the printed pack, and see our parents’ guide.

Does it need a microwave?

No. Water only — here is the full list of kits like that.

How long does the pack keep?

It is a dry powder with a long but not unlimited life. We wrote up shelf life and storage.

Where to get it We stock this one and post it from Tokyo — Suppai Lemon Jelly is here. The rest of the range is on our DIY Candy Kits page, and the full set of English guides is in our English instructions for every kit.
Posted from Tokyo Every kit we send is the Japanese retail product, with Japanese packaging. That is why we write these guides — the instructions in the pack are diagrams plus Japanese text, and the diagrams only get you so far. Meiji Chewing Gum makes this one — it is a different company from Kracie, the maker of Popin' Cookin', but the kits work the same way: Japanese retail packaging, numbered pictures, and instructions in Japanese only.
