Pulled pork in slow cooker

[Jujuheyhey]

I got a shoulder of pork on offer today so going to do it in the slow cooker. Never tried it before but I've read a few recipes and know the basics - bed of onions, add some liquid, cook on low for 8 hrs, take it out and shred, add bbq sauce and cook for another hour.

But I'm still a bit confused! There seems to be so many variations. What do you wise people of MN do?

Do I need to rub any spices in before cooking? If so, which? Overnight or just before? Should I sear it?

What liquid works best? Coke/stock/water?

Homemade BBQ sauce - where do I start? Or should I just get a bottle? If so will any do? I've got some cheapo Asda stuff in a squeezy bottle but that doesn't seem right somehow...

I rub it with a spice mixture (Mumsnet Top Bananas book recipe) that includes smoked paprika, brown sugar, salt, pepper, but could have stuff I've forgotten.
Place in slow cooker, no onions, add a glass / 250ml or so of apple juice. All day on low.
For the Sauce I 'played it safe' and used a standard Heinz one, just use whichever one you like the taste of.
Yum, always a success!

You don't need to add liquid if it's supermarket pork - quite a lot of water comes out of it anyway. I just add brown sugar.

My favourite recipe for the sauce.

2 tbsp demerara sugar
2 tbsp Worcecester sauce
1 tbsp American mustard
2tbsp tomato ketchup
1 tbsp cider vinegar

Mix together and pour on top of pork before cooking.

Delicious.

i never cook any longer once it's shredded.

I rubbed in smoked paprika, brown sugar and a bit of salt. No liquid. It's on low but bit worried I didn't put the lid on properly and it's not been cooking properly since 9am

Might try and make my own BBQ sauce but have a bottle as back up just in case...

9 hours in the slow cooker on low and it's as tough as old boots
