The HTML code on your posts is incredibly corrupted, as if you had been copy/pasting from the very worst version of Word that ever existed. For example:
<p>Pre-heat the oven to 190C - gas 5.</p>
<p>Boil water and salt.</p>
<p>Peel and cut the potatoes in half; wash them in warm water.</p>
<p>Place the potatoes in the salty water and leave to boil for 5-7 minutes.</p>
<p>Drain the water and shake the pan to roughen up the potatoes a bit.</p>
<p>Rub some oil on a large roasting pan and lay the baking sheet on top. Add 4 tablespoons of olive oil to the baking sheet and spread the potatoes over it, coating the potatoes with the oil.</p>
<p>Place in the oven and cook for 40 minutes or until they are turning nice and brown</p>
<p>Serve with gravy.</p>

That's just appalling.
To fix this, and to prevent it from happening again, go to your dashboard Settings->Writing page and select "Wordpress should correct invalidly nested XHTML" and save.
Then go to Dashboard->Posts and select the most recent posts, all of them. Set them to Draft using the bulk editor (the drop-down button there, you'll see it). Set them back to Public. This forces the change above to take effect.
That should fix this and prevent it from happening again.
