Chilled colorful agar-agar noodles with savory soy dipping sauce for a playful, vibrant dish.

# What You'll Need:

→ Neon Agar-Agar Noodles

01 - 2 1/8 cups water
02 - 0.25 ounces agar-agar powder
03 - 1 tablespoon sugar
04 - Food-safe neon gel or liquid food coloring, assorted colors

→ Dipping Sauce

05 - 1/3 cup soy sauce or tamari (for gluten-free)
06 - 1 tablespoon rice vinegar
07 - 1 tablespoon mirin
08 - 1 teaspoon sesame oil
09 - 1 teaspoon freshly grated ginger
10 - 1 teaspoon sugar
11 - 1 scallion, finely sliced
12 - 1 teaspoon toasted sesame seeds (optional)

→ Garnish

13 - Microgreens or edible flowers (optional)

# How To Make It:

01 - In a saucepan, combine water, agar-agar powder, and sugar. Heat over medium, stirring constantly until agar-agar is fully dissolved and mixture boils, about 2 to 3 minutes.
02 - Remove from heat and divide the hot mixture into separate bowls according to the number of desired colors. Add a drop or two of neon food coloring to each and stir well.
03 - Using a syringe or squeeze bottle, pipe the colored agar mixtures into a bowl of ice water, forming noodle-like strands. Let them set for 1 to 2 minutes until firm. Alternatively, pour the mixtures into a flat tray, allow to set, then slice into thin noodle strips with a sharp knife.
04 - Collect the agar noodles and rinse briefly under cold water. Drain thoroughly and refrigerate until ready to serve.
05 - Whisk together soy sauce or tamari, rice vinegar, mirin, sesame oil, grated ginger, and sugar in a small bowl until sugar dissolves. Stir in sliced scallions and sesame seeds, if using.
06 - Arrange the chilled neon agar noodles in small bundles on serving plates. Garnish with microgreens or edible flowers as desired and serve alongside the dipping sauce.

# Expert Suggestions:

01 -
  • The surprise of that delicate, bouncy texture stops people mid-bite in the best way.
  • It's vegan and naturally gluten-free, so you're not scrambling to modify it for guests with dietary needs.
  • Takes less than 40 minutes from start to impressive presentation.
02 -
  • Agar-agar sets at room temperature, not just in the fridge, so don't panic if ice water alone doesn't seem to be doing the job—it will firm up within a minute or two.
  • The color intensity matters: gel coloring gives you those neon, almost luminous tones, while liquid food coloring can look a bit washed out by comparison.
  • If your agar mixture starts to set before you finish piping, just reheat it gently—it re-melts and re-sets without losing anything.
03 -
  • Keep your ice water ice-cold and refresh it between batches so your noodles set firm and stay translucent.
  • Don't overthink the color combinations—even just two or three neon shades create a stunning visual impact without looking chaotic.
