McVitie's has changed the recipe of its chocolate digestives after almost 100 years. And despite its claims to have added 3% more chocolate, Which? taste testers say it is no improvement.
So is this digestive really so unpalatable, or are we just bad at accepting change?
The results emerged in a taste test of chocolate digestive biscuits. The consumer group asked 30 regular biscuit eaters to compare the old and the new: some 19 out of 30 testers said that the old biscuit was better. This could be a blow for the firm, as this particular biscuit sells 81 million packets a year in the UK - which is a lot of sales to lose.
The new biscuit was said to be less crunchy, and the topping less wavy. United Biscuits, however, insists that the recipe for the biscuit has not changed in any way - it's just that more chocolate has been added to the coating.
Bad at change
We are not always great at accepting changes to foods we have come to love. We have been eating McVitie's digestives made from the same recipe since 1893. We have been eating the same chocolate digestives since 1925. After almost 100 years, it wasn't going to be easy to persuade us to embrace change.
There was similar dissatisfaction back in 2005 when Heinz bought HP sauce and reduced the salt content by 38% - changing the taste dramatically - we have got used to it since.
However, companies don't always get away with it. Twinings faced a backlash after changing its Earl Grey recipe to add more lemon. The resulting outcry persuaded them to bring back Classic Earl Grey alongside the new recipe.
The most famous u-turn was in 1985 when as the result of taste tests, Coke changed its recipe. The response brought about a swift re-think, and within three months Classic Coke had returned.
As for these chocolate biscuits, the solution is going to be to try it for yourself, and ask yourself whether more chocolate is such a bad thing.
The good news is that if you are disappointed, there are plenty of alternatives. Before this taste test, Which? had previously tested the original biscuit against supermarket own-brands. And while the original came out on top, it was also decidedly more expensive.
Its nearest rival was a three-way-tie between Best Buys Lidl Tower Gate, Essential Waitrose, and Sainsbury's Milk Chocolate Digestive.
Given that McVitie's costs £1.75, and the Lidl rival just 59p per pack, it's food for thought for biscuit lovers reconsidering their allegiances.
But what do you think? Can you get used to more chocolate, or will this change tea time as we know it? Let us know in the comments.
10 of the biggest consumer rip-offs

Using a mobile phone to make and receive calls, send texts and browse the web while abroad can be extremely costly – especially if you are travelling outside the European Union (EU), where calls can cost up to 10 times as much as at home.
To avoid high charges, Carphone Warehouse suggests tourists ensure a data cap is in place, use applications to check data usage, turn off 'data roaming', avoid data-intensive applications such as Google Maps and YouTube and use wi-fi spots to update social networking sites.
Payment Protection Insurance (PPI) is supposed to help people to continue meeting their loan, mortgage or credit card repayments if they fall ill or lose their jobs. However, policies are often over-priced, riddled with exclusions and sold to people who could not make a claim if they needed to.
At one point, sale of this cover - which was often included automatically in loan repayments - was estimated to boost the banks' profits by up to £5 billion a year.
Now, though, consumers who were mis-sold PPI can fight back by complaining to the bank or lender concerned and taking their case to the Financial Ombudsman Service (08000 234567) should the response prove unsatisfactory.
It could be you, but let's face it, it probably won't be. In fact, buying a ticket for the Lotto only gives you a 1 in 13.9 million chance of winning the jackpot.
With odds like that, you would almost certainly be better off hanging on to your cash and saving it in a high-interest account.
No-frills airlines such as EasyJet may promote rock-bottom prices on their websites. But the overall fare you pay can be surprisingly high once extras such as luggage and credit card payment fees have been added - a process known as drip pricing.
Taking one piece of hold baggage on a return EasyJet flight, for example, adds close to £20 to the cost of your flight, while paying by credit card increases the price by a further £10.
It may therefore be worth comparing the total cost with that of a flight with a standard airline such as British Airways.
Cash advances, which include cash withdrawals, are generally charged at a much higher rate of interest than standard purchases.
While the average credit card interest rate is around 17%, a typical cash withdrawal of £500, for example, is charged at more than 26%.
What's more, as the interest accrues from the date of the transaction, rather than the next payment date, costs will mount up even if you clear your balance in full with your next payment.
Supermarkets such as Tesco and Asda often run promotions under which you can, for example, get three products for the price of two.
However, it is only worth taking advantage of these deals if you will actually use the products. Otherwise, you are simply buying for the sake of it, which is a waste of your hard-earned cash.
Buy a train ticket at the station on the day of travel and the price is likely to give you a shock - especially if you are travelling a long distance at a busy time of day.
However, you can cut the cost of train travel by 50% or more by going online and making the purchase beforehand - especially if you book 12 weeks in advance, which is when the cheapest tickets are on sale.
Other ways to reduce the price you pay include avoiding peak times and taking advantage of so-called carnet tickets, which allow you to buy, for example, 12 journeys for the price of 10.
Most High Street banks offer packaged accounts that come with monthly fees ranging from £6.50 up to as much as £40, with a typical account charging about £15 per month.
Various benefits, such as travel insurance and mobile phone insurance, are offered in return for this fee. But whether or not it is worth paying for them depends on your individual circumstances.
