Peppercorn sauce in a pub syns question

[maypole]

Last night I went to local for food.

I had a steak with jacket but my friend who works there put me some peppercorn sauce on the side which I then poured all over my steak

Does anyone know how much I should put down for it?

Thanks in advance x

I also scoffed about 8 squares of
Green & Black's 72% Cooks Chocolate Bar, Organic 150g bar

42½ Syns on Extra Easy

Original 42½ Syns

Green 42½ Syns
​

While I was trying to make the giant jaffa cake so if anyone can suggest how many syns 8 squares would be I would be very grateful??
