MOSHIO / 藻塩

Why Moshio Tastes Different

Moshio is sea salt made with seaweed. It does not just season food — it helps simple food taste fuller, deeper and more complete.

Use it on rice, eggs, vegetables, fish, meat, potatoes or buttered toast.

Most salt sharpens. Moshio deepens.

1. Sea salt with umami depth

Ordinary salt often gives food a sharp hit of saltiness. Moshio gives a softer, rounder finish.

Because it is made with seaweed, it carries a quiet savoury depth that helps ingredients taste more complete.

That is why it works so well on simple food: warm rice, eggs, vegetables, fish, potatoes, grilled meat, avocado, tomatoes and buttered toast.

2. A Japanese pantry discovery

Moshio comes from an older Japanese way of thinking about food: simple ingredients, handled carefully, used with attention.

RETTO’s first Moshio comes from Tsushima, an island between Japan and Korea, where the sea is part of daily life.

Sea salt. Seaweed. Craft. Place. That is the blend that gives Moshio its difference.

3. Why it performs

Moshio is not just about making food salty. It elevates taste — bringing out more sweetness, savoury depth and natural character from simple everyday food.

Clean saltiness

A clear, gentle seasoning that lifts food without harshness or sharp edges.

Gentle umami

Seaweed adds a quiet savoury note that gives food more depth.

Mineral character

Naturally occurring minerals give Moshio a warmer, fuller taste than ordinary refined salt.

Everyday elevation

A small pinch can elevate rice, eggs, vegetables, fish, meat, toast and many other everyday foods.

4. An everyday ritual

Finish with Moshio. Taste, pause, then adjust.

Add a pinch.

Taste and pause.

Adjust only if needed.

This is not about adding more saltiness. It is about noticing how one better ingredient can elevate simple food.

5. How to use Moshio

Eggs: scrambled, boiled or fried.

Vegetables: tomatoes, cucumber, greens or roast veg.
