A lot of anglers enjoy fishing with chopped worm and caster, but you can enhance your catching potential if you create stodgy worm-packed balls, encased in a thin film of groundbait - and I've found Sonu's F1 Groundbait to be perfect for this.

F1 Groundbait is made up of a blend of fishmeals and crushed pellets, plus it has a unique sweet attraction. The fine texture also means you can mix it to a sticky consistency and it is worm-friendly.
In the past a lot of continental groundbaits were ruled out for mixing worms into because of their high salt content, which soured and killed the worms instantly.
But F1 Groundbait does not damage the worms and that's great news.
A lot of anglers mix some groundbait and then add the worms to the feed.
I happen to think this is the wrong way of doing it.
I will get a couple of big handfuls of worms and put them in a three- pint bait tub, finely minced. I then add the groundbait to the worms and this creates a stodgy mix, which has an irresistible pull when introduced.
People often ask me how I mix my groundbait and with F1 Groundbait it is straightforward.
I mix it on the bank on arrival at my peg. After putting my seatbox down I'll immediately mix the groundbait and leave it to settle. After half an hour I'll have a look at it, mix my fingers through it and add a bit more water.
You need to be careful with fishmeal-based groundbaits when mixing them, because they can be ruined if you add too much water all at once. When I am happy with my mix, I will push it all through one of the blue Preston maggot riddles, and it is ready for use.
Another good thing about F1 Groundbait is that once mixed properly, it doesn't seem to dry up.
All I do to keep mine in tip-top shape during a  match is to place a dampened towel stretched over the bucket. This keeps the groundbait cool and in good order.
