Sangaste Rye Starter

Nordic rye starters — known as juuri or raski in Finland, both meaning 'root' — are the foundation of traditional rye sourdough bread. Built from just flour and water, this living culture captures wild yeast and bacteria to create deep flavor, natural leavening, and bread that stays fresh for days. We use our Sangaste Rye for this one — a heritage variety sourced directly from Finland and stone milled whole grain here in Gilbert. It ferments quickly and develops the robust, earthy aroma characteristic of classic ruisleipä — Finnish rye bread.

What You'll Need

Sangaste Rye Flour (325g total)

Water, room temperature and non-chlorinated (325g total)

Directions

DAY 1 — MIX

100g Rye Flour

100g water

Stir together into a thick, porridge-like paste. Cover loosely and rest at room temperature.

DAY 2 — FEED

Add:

50g Rye Flour

50g water

Mix well and keep covered.

DAY 3 — BUILD

Discard half, then add:

75g Rye Flour

75g water

Stir to a thick batter. By now the aroma should be turning pleasantly tangy.

DAY 4 — STRENGTHEN

Discard half, then add: 100g Rye Flour

100g water

Your starter should be bubbly and just slightly risen.

DAY 5 — READY

Your starter is active and ready to use when it smells clean and sour, shows steady bubbling, and rises and falls predictably between feedings.

TEXTURE GUIDE

A healthy rye starter is thick — like wet clay, not pourable batter. It should be slightly sticky and dense.

HOW TO USE

Feed once and use at peak activity for rye breads, porridges, or sourdough builds.

STORAGE

Keep at room temperature and feed daily for regular baking. For longer breaks, refrigerate and refresh before use.

TRADITIONAL TIP

To preserve your starter the way Finnish bakers have for generations, spread a thin layer on parchment, let it air dry completely, then crumble and store in a cool, dry place. It will keep for months and come back to life with just a little flour and water.
