Jeg kunne også sagtens suge noget Janssons fristelse.
Blev SJUKT sugen på Janssons frestelse nu 🤤
One of Sweden’s most delicious exports, Jansson’s temptation, otherwise known as Janssons frestelse, is a creamy potato casserole with melty onions and umami-packed tinned sprats.

Yesterday, at 04:55am my wife gave birth to our second son. At 4230g and 55cm, Walther, is the exact same size as his big brother, Eske, when he was born almost four years ago.
That’s all, folks.

This Volvo ad hits hard.
The White House is asking people not to share pictures of the East Wing because it’s even worse today.

Meget kan sikkert siges om det danske sundhedsvæsen, men fødeafdelingen på Holbæk sygehus ved tilsyneladende hvordan man laver tarteletter og smækker en gang stroganoff sammen.

The West Tofts hand axe, with its fossilised shell, is one of the most popular objects on display at MAA. It has been assumed that the position of the shell was an aesthetic choice by the axe's creator, but this interpretation has been challenged. What do you think? 1/2

I just got the final batch of data for my PhD-thesis:
d13C, d15N and d34S values for 28 Late Iron Age and Viking Age sheep from Denmark - which adds to a surprisingly limited existing dataset of just about a small handful of ovine isotope samples.
