Frankfurt green sauce / Frankfurter Grüne Soße from Germany is a creamy blend of fresh herbs, yogurt, sour cream, and oil that is usually served cold with hard-boiled eggs, boiled potatoes (great with roasted potatoes too) or meat. Traditionally it is made of seven different kinds of herbs: borage / Borretsch, chervil / Kerbel, cress / Kresse, parsley / Petersilie, salad burnet / Pimpinelle, sorrel / Sauerampfer and chives / Schnittlauch. I simply used a mixture of fresh herbs and greens, so put together your own mixture if you cannot find all the taditional herbs.
This healthy combination of seven tasty and finely balanced herbs was one of Johann Wolfgang von Goethe's favourites. A famous myth is that this sauce was invented by his mother. Actually, the first green sauce recipe was published in 1860 in a cookbook by Wilhelmine Rührig.
This distinctive green sauce is a perfect bold partner for those roasted purple potato wedges. This recipe will probably make more green sauce than you need but it is delicious on many things, such as toasted sourdough bread, roasted carrots, pumpkins or bbq chicken.

- Preheat oven to 200C/400F. Line a large baking tray with parchment paper.
- Wash, dry and cut the purple potatoes into quarters lengthways. Place potato wedges in a large bowl and cover with cold water. Set aside for 30 minutes. This allows for some starch to be released. Drain well and pat potatoes dry in a clean dry tea towel. Transfer to a bowl, add in olive oil and toss to coat the potato wedges in the oil.
- Spread the potato wedges evenly onto the prepared tray. Roast in oven for 15 minutes, then turn pieces over. Roast for a further 10-15 minutes, until the skin is crispy and crunchy and flesh is fork tender.
- Meanwhile prepare the sauce. Finely chop fresh herbs and puree together with sour cream, yoghurt, olive oil, lemon juice, salt, and pepper with an immersion blender.
- Spoon some green sauce on the serving plates, top with potato wedges and sprinkle some coarse salt over. Garnish with dried cornflower and green chilli rings if using.

Angie, before I even got to the end of your post... I thought wow, you could use this green sauce for so many things. Definitely love the sauce and the purple potatoes-not always easy to find. btw, love the photograph. The purple really stands out.
These purple potatoes are incredible!
I'll bet that's good, we like those purple taters!
...I've never had purple potatoes.
I bet this sauce tastes good with potatoes. I haven't heard of this green sauce, but it sounds yummy.hugs-Erika
Wow purple potatoes!
What beautiful colours on a plate. The green sauce must taste fantastic with that combination of herbs.
Angie, I do like roasted purple potatoes...and other varieties as well. However, I'd like them with a nice pork chop or a rack of lamb. You had 5 eggs and a big ribeye for breakfast!? Wow! My kind of early morning wake me up... Take Care, Big Daddy Dave
Very colourful
Such purplish potatoes. Never seen it. Even the skin is deep purple.
I like sweet potatoes, especially those yellow Japanese type.
Yum yum. Loks stricking. The green sauce is a great idea and I love hearing about these kind of local foods.
Oh, have always loved the 'Frankfurter Sosse' but make it a tad less fatty . . . I grew up on pink and blue potatoes in Europe - can get the purple ones here in Australia but only at specialist greengrocers . . . yes, great with the sauce but I often use the latter with fish balls > lovely !!!
very delicious thanks for posting going to try this I have heard alot about how healthy this super food greens are

Thank you for sharing.
Hello,
Another yummy dish, I have tried the purple potatoes they are good.
Thanks for sharing. Have a great weekend.
Purple and green is one of my fave colour combos ever! Sadly, we don't have either purple potatoes here nor purple carrots, even the batat potato, the sweet potato is quite expensive compared to the regular one.
Angie, this dish is a delight for the eye as well as the palate. It almost looks like it should be served for Mardi Gras., Bernadette, New Classic Recipe
I've never had or seen purple potatoes, so pretty and the green sauce sounds amazing!
Estoy segura que esa salsa con historia, le va divina a estas preciosas patatas.

I've never heard of this sauce before, but it sounds like a delicious and healthy combination of fresh herbs, yogurt, sour cream, and oil. I appreciate that you provided some background on the history and traditional ingredients of the sauce, as well as suggestions for alternative herbs and ways to use any leftover sauce.

The green sauce sounds wonderful. I like purple potatoes too.
Judee from Gluten Free A-Z : I LOVE potatoes and the purple ones are so intriguing but very expensive here. I'll be they are delicious in that incredible herbed sauce.
Love purple potatoes and purple sweet potatoes. Flip side is - they are usually more expensive than the red, and white variety
