Chocolate orange sherbet slice

Chelsea's favourite sweet from her new book Eat. The silky richness of the chocolate fudgy part is balanced by the tart sherbet — a zing in every bite!


My favourite sweet in the book! I’m a choc-orange fiend and I’ve been wanting to create a jaffa-type slice for ages now. I wasn’t quite sure where I was heading when I started out, but eventually things clicked into place and here we are. The silky richness of the chocolate fudgy part is balanced by the tart sherbet — a zing in every bite! You’ll have quite a few oranges left sitting naked and vulnerable after you’ve made this. I just squeeze mine and we drink the juice with a few cubes of ice at breakfast.

250g malt biscuits
100g butter, very soft
¾ cup rolled oats
¹∕³ cup sweetened condensed
zest of 1 orange
¼ tsp salt

500g dark chocolate, chopped
(about 50–60% cocoa)
250ml cream
zest of 3–4 oranges
100g butter, cubed
1 tsp natural orange essence
½ tsp salt

zest of 2 oranges, plus extra to sprinkle
½ cup icing sugar
½ tsp tartaric acid
¼ tsp citric acid
¼ tsp salt


Line a 20cm square slice tin with baking paper so it goes up the sides.

Crumble the biscuits into a food processor. Process to a fine crumb. Add the remaining base ingredients and process to combine (I find tilting the processor helps it blend better). If you don’t have a food processor, you can smash the biscuits up in a clean tea towel with a rolling pin and then mix the other ingredients in afterwards.

Press the crumb firmly in an even layer into the prepared tin. Set aside.

Put the chocolate, cream and orange zest in a glass or ceramic mixing bowl and microwave on high for 1 minute 30 seconds. Stir to melt the chocolate. You can pop it in for another minute or so if it needs it. Add the butter and stir briskly to combine.

Lastly, stir through the orange essence and salt. Spread the topping over the base.

To make the sherbet, either blitz everything in a small food processor or finely chop the zest and combine with the other ingredients in a bowl. Sprinkle over the chocolate topping, add the extra zest, cover and refrigerate for at least 4 hours until firm, then slice. You’ll have extra sherbet, so either sprinkle on some more when serving the slice, or keep in a container and just stick your finger in and eat it every now and then.

Keep this slice in the fridge as the topping will go soft in warm weather. It will keep in an airtight container for up to a week. You can also freeze it.

Fudge cake slice

This recipe has been a fan favourite for over a decade. Cut it into slices for the kids or into tiny squares as a treat with your cuppa. It also freezes well, so you can stash a few squares away for when no one is looking.

Lasagne soup with cheesy garlic melts

This hearty soup is a proper hug in a mug. The ricotta and Parmesan topping really fulfills the 'lasagne' promise, but if you don’t want to bother you can just top it with grated cheese and it’ll still be a winner. The super-cheesy garlicky toasties are a good addition to any tomatoey soup — or just eat them on their own!

Chocolate, tahini banana bread

I have been making a banana bread with chocolate and tahini on repeat for a while now, and every time I’ve eaten it over the last year or so, I couldn’t help thinking that the particular combination of intense chocolatiness, sweet, texture-softening banana and the rich earthiness of tahini would make the perfect warm pudding.

Chicken in a pot with lemon and orzo

This is not exactly the same as perhaps the most precious recipe in my repertoire, My Mother’s Praised Chicken, which found a home in my eighth book, Kitchen, but it owes a lot to it. A family favourite, it’s a simple one-pot dish which brings comfort and joy, and it is my pleasure to share that with you.

Snausage Rolls

Sausage rolls will always be über-cool, no matter what anyone says. They're always the first to be nabbed at morning tea, classily dressed-up with a generous splurt of store-bought tomato sauce... crispy, juicy little taste bombs. 

My kinda butter chicken

With fragrant spices, tomatoes, cashew butter and yoghurt.

Easiest broccoli quiche

Crispy salmon tacos

Autumnal vegetable soup with basil, garlic & olive oil

One of the rather pathetic realities of the fact that so many of the restaurants in France are disappointing these days is the almost tearful joy in finding one that’s everything you would have hoped for, often from your childhood or teenage memories. Such a place is Le Bistro du Paradou near Arles.

Spicy sprout and mushroom noodles with five-spice

Sprouts (and the whole brassica family) go fantastically with Asian flavours. Out of season, use a mix of the rest of the brassicas – broccoli, cauliflower, kale, cabbage, spring greens etc. You could also make a spring version with asparagus and peas.

Tuscan chicken casserole

We ate many dishes similar to this while spending time in Italy and they were all different depending on the part of Tuscany that we were in. This is our version of a Tuscan chicken casserole and it’s very moreish and flavoursome. I love it in the winter and any leftovers get tossed through some pasta the next day.

Portobello steaks and butter bean mash

A vegetarian recipe that is simply as good as any steak (with mash), if not better.
