It's an East Frisian Cage Match!
I did a taste test between Harney & Sons 'East Frisian' and the recommended BĂĽnting Tee 'Bio Original Ostfriesentee'
5g ea for 4 min at 212f/100c, actual Kluntje used (5g ea), and the thickest cream from the farm up the road
Summary: BĂĽnting is more rounded and less sharp than H&S but they are very similar and once you get down to the sugar level, you cannot ascertain a difference. Both are excellent! I will add that since I am in the US, I did get stuck with paying tariffs for the tea. The sugar is actually available at Harney & Sons
I am going to be WIDE AWAKE now, lol
