I tried supermarket tomato ketchups - a 90p winner tastes as good as Heinz

Heinz Tomato Ketchup

There is no denying the perfect taste of this iconic sauce.  It's made with real sun ripened tomatoes, rather than cheaper substitutes.  Simple and delicious although saltier than most and very expensive compared to all  the others.

Essential Waitrose Tomato Ketchup

The sauce is an appetising vibrant red with a lovely sweet and sour aroma. The flavour is subtle and inoffensive, and I enjoyed the fresh, tangy flavour of the tomatoes.  A good price from Waitrose for a quality-tasting sauce.

Morrisons Tomato Ketchup

Middle of the road sauce. This had the lowest salt content and less than average levels of sugar but the flavour was too weak and the texture  a bit watery.  The colour was too dark too.

Tesco Tomato Ketchup

The squirty lid really doesn't work very well and you end up with waste. Taste-wise it's not great either. It's watery with strong garlic and onion notes and Worcestershire sauce vibes.

Asda Classic Tomato Ketchup

Taste-wise, it's the closest match to Heinz. If anything, it had a bit too much garlic. The thickness was nice and it's good value. Slightly lower in sugar and salt than the market leader, too.

Aldi Bramwells Tomato Ketchup

A lovely texture and colour, but I found it quite sweet and it does contain more sugar than most. It was a bit too tangy and a little on the runny side, but overall not a bad choice and excellent value.

Sainsbury's Tomato Ketchup

This had a lovely texture and tastes as good as Heinz. It was less sweet and watery than many of the other own-brands and as it contains less sugar and salt, it's healthier too. A winner all round.
