"Spring"? Well, these varieties were on the shelves on 1st February, so I guess so. The snow outside must just be an illusion.
We've had Johannisbeer-Streusel two years in a row, so no need to recapitulate its excellence (8.5/10). Buttermilch-Zitrone is also a well-known combo, though is more usually encountered during the summer months. Two new ones, though, one of which (Waffel) is not actually a spring variety, but a new addition to the regular line-up.
Haferkeks + Joghurt: 7/10
The crunch is very nice, but the yoghurt filling is not a favourite of mine, as it just tastes a bit too fake. So this one gets a compromise rating.
This one comes with a health warning: do not, under any circumstances, use the usual Knick-Pack technique to open this Ritter Sport. If you do, the whole package will explode, showering bits of waffle and chocolate everywhere. The structural unsoundness of this variety (plus the fact that I only ate about half of it, and the rest is still irretrievably lodged in dark corners of my sofa) contributes to my not-very-complimentary rating, which is probably unfair as far as taste and mouthfeel are concerned. Approach with caution.
