New Yorkshire pudding tins!! Stuck puddings!! Help!!

[bossboggle]

Have had to buy some new pudding tins, mine were worn out!! New tins and stuck puddings - driving me NUTS any advice on how to make sure they don't stick?? Getting fed up - never stuck in old tins, mind you they were seasoned, well seasoned!! Help!!

We have found that using a bit of butter rather than oil/lard works much better for ensuring the Yorkshires don't stick - a bit naughty but nice
