Why split peas win me over
Split peas are my go-to for this soup. They cook faster than whole ones and don't need soaking first. Their gentle nutty flavor makes the soup extra creamy and flavorful.
Mustard makes magic happen
A spoonful of mustard isn't optional in my Hernekeitto. It brings a tangy kick that really lifts the pea flavor. This tiny addition makes the soup truly authentic.
My sweet caramelized pearl onions
Those pearl onions are my favorite topping ever. As they slowly caramelize, they develop this wonderful sweetness that matches the savory soup perfectly. They turn every serving into something special.
A dish for the whole family
Everyone seems to like this soup. It fills you up, packs nutrients, and can be seasoned just how you like it. It's true comfort food that brings everyone to the table.
Local and earth-friendly
I try to use ingredients from nearby farms. Peas, carrots and celery aren't just good for the planet – they taste way better too. That's what makes mindful cooking so rewarding.
Great for meal prep
My Nordic pea soup actually tastes better the next day. It stays good in the fridge for three days without problems. That means easy, stress-free meals during busy weeks.

A treat for every sense
When the smooth soup meets crispy onions and hearty rye bread, your taste buds will throw a party. The bright colors and mouthwatering smell will leave you wanting seconds right away.

With its rustic charm, this soup always wows my guests. It looks fantastic and tastes even better. It's a dish that never fails to impress.

Don't worry about the ingredient list looking long. The cooking part's really easy. A few simple steps and you'll have a delicious soup that tastes like you spent hours in the kitchen.
Comfort on cold days
When the weather turns chilly, this soup becomes my soul food. It warms you from inside, gives you energy, and brings a bit of Nordic coziness right into your kitchen.
My own twists
I like to play around sometimes. Maybe add extra Liquid Smoke for deeper flavor or swap in roasted shallots instead of pearl onions. Each version has its own special charm.
Nutritious and filling
This soup isn't just yummy – it's packed with goodness too. Fiber, protein and vitamins make it a complete meal that keeps hunger away for hours.
A taste of Finland
Each spoonful brings a little Finland into my home. It captures the simplicity and warmth of Nordic cooking with flavors you won't forget.

My final thoughts
My Hernekeitto goes beyond being just soup. It's a piece of Nordic tradition that warms both heart and belly. It's a dish I love cooking again and again that never loses its special touch.
